Hollow atoms are a concept in atomic physics that refers to atoms that have had one or more of their inner electrons removed, creating a sort of "hollow" structure. This can happen in highly ionized states, where electrons from the inner shells are ejected, leaving behind only outer electrons. The properties of hollow atoms can be quite interesting because the absence of inner electrons influences the atom's electron distribution, energy levels, and interactions with other particles.

Electron configurations describe the distribution of electrons among the various atomic orbitals of an atom. Each electron configuration follows a prescribed order based on the Aufbau principle, Hund's rule, and the Pauli exclusion principle. Here is a list of the electron configurations for elements from hydrogen (atomic number 1) up to a selection of some higher atomic numbers: 1. **Hydrogen (H)**: 1s¹ 2. **Helium (He)**: 1s² 3.

BASIC Atom refers to a simplified or compact version of the BASIC programming language, which stands for Beginner's All-purpose Symbolic Instruction Code. BASIC was created in the 1960s to provide an easy introduction for beginners to computer programming.

The atomic nucleus is the small, dense region at the center of an atom that contains most of the atom's mass. It is composed of two types of subatomic particles: protons and neutrons. - **Protons** are positively charged particles, and their number determines the atomic number of an element, which defines the element itself (e.g., hydrogen has one proton, while carbon has six). - **Neutrons** are neutral particles, meaning they have no charge.

Atomic mass, also known as atomic weight, is the weighted average mass of an atom of an element, measured in atomic mass units (amu). It reflects the mass of an atom relative to the mass of carbon-12, which is assigned a value of exactly 12 amu. Atomic mass takes into account the relative abundances of the different isotopes of an element in nature and their respective masses.

Atom can refer to several different concepts depending on the context: 1. **Science/Chemistry**: In the scientific context, an atom is the basic unit of matter and the defining structure of elements. Atoms consist of a nucleus made of protons and neutrons, surrounded by a cloud of electrons. Different combinations of atoms form molecules, which make up all substances. 2. **Text Editor**: Atom is also a popular open-source text and source code editor developed by GitHub.

A 1s Slater-type function is a mathematical function used in quantum chemistry and atomic physics to describe the spatial distribution of electrons in an atom, particularly for the innermost shell of electrons (the 1s orbital). Slater-type orbitals (STOs) are defined by their exponential decay and can be used to effectively approximate the wavefunctions of electrons.

Subatomic particles are the fundamental building blocks of matter that are smaller than an atom. They include various types of particles, each with its own properties and roles in the structure of matter. The main categories of subatomic particles are: 1. **Protons**: Positively charged particles found in the nucleus of an atom. The number of protons determines the atomic number and the identity of the element.

Exotic atoms are a class of atomic systems that differ from ordinary atoms in that they contain at least one particle that is not typically found in standard atomic structure. In most atoms, protons, neutrons, and electrons are the building blocks. However, in exotic atoms, one or more of these particles are replaced or modified by other types of particles.

Chemical elements are pure substances that cannot be broken down into simpler substances through chemical reactions. Each element is defined by the number of protons in its atomic nucleus, which is known as the atomic number. For example, hydrogen has one proton and an atomic number of 1, while carbon has six protons and an atomic number of 6. Elements are the basic building blocks of matter and form the foundation for all chemical compounds.

The atomic radius is defined as the distance from the nucleus of an atom to the outer boundary of its electron cloud, where the probability of finding an electron is significant. It is a measure of the size of an atom and can vary depending on the atom's environment and bonding with other atoms.

The Variable Energy Cyclotron Centre (VECC) is a premier research institute located in Kolkata, India. It is part of the Department of Atomic Energy (DAE) of the Government of India. VECC is primarily involved in the study of nuclear and particle physics, and it is notable for its development and operation of cyclotron facilities. The centre is equipped with a variable energy cyclotron that allows researchers to accelerate ions over a range of energies for various experimental applications.

SST-1, or Steady State Superconducting Tokamak-1, is a fusion research facility developed by the Institute for Plasma Research (IPR) in India. It is designed to study and advance the tokamak concept, which is one of the most promising methods for achieving controlled nuclear fusion.

"Parmanu" typically refers to a few different concepts depending on the context, but it is most commonly associated with the following: 1. **Film**: "Parmanu: The Story of Pokhran" is a Hindi film released in 2018 that tells the story of India's nuclear test at Pokhran in 1998. The movie stars John Abraham and revolves around the challenges faced by the Indian government and scientists in conducting the tests.

The Indira Gandhi Centre for Atomic Research (IGCAR) is a premier nuclear research facility located in Kalpakkam, Tamil Nadu, India. Established in 1971, it is named after Indira Gandhi, the former Prime Minister of India. IGCAR operates under the Department of Atomic Energy of the Government of India and plays a significant role in India's nuclear research and development efforts.

ADITYA is a tokamak, which is a device designed to confine plasma using magnetic fields in order to achieve controlled nuclear fusion. It is a part of India's efforts in fusion research and is primarily developed by the Institute for Plasma Research (IPR) in Gandhinagar, Gujarat.

A wind profiler is a specialized meteorological instrument used to measure wind speed and direction at various altitudes in the atmosphere. It operates by emitting a radar signal that interacts with particles in the air, such as dust, moisture, or insects. The profiler can detect the backscattered signals from these particles, which allows it to determine the vertical profiles of wind speed and direction at different heights.

A weather balloon is a type of high-altitude balloon specifically designed to collect data about the atmosphere. Typically made of latex or synthetic rubber, these balloons are filled with helium or hydrogen gas and can ascend to altitudes of up to 40 kilometers (about 25 miles) or more. Weather balloons are equipped with scientific instruments, such as radiosondes, which measure various atmospheric parameters, including temperature, humidity, atmospheric pressure, and wind speed and direction.

Richard Assmann (1845–1918) was a German meteorologist and professor known for his contributions to the field of meteorology and atmospheric science. He is particularly famous for his work on the theory of atmospheric pressure and for formulating the Assmann psychrometer, which is an instrument used to measure humidity. His research and developments have had a lasting impact on the study of weather and climate.

A radiosonde is a type of weather balloon equipped with meteorological instruments that are used to measure various atmospheric parameters as it ascends through the atmosphere. Typically, it collects data on temperature, humidity, pressure, and wind speed and direction. The radiosonde is attached to a balloon filled with helium or hydrogen, which allows it to rise to altitudes of up to 30 kilometers (about 19 miles) or more.
