What is electrons affinity?

Electron affinity is the measure of energy released when the neutral atom absorbs the electron. The absorption of another electron requires energy because the negatively charged particles naturally do not attract a neutral atom. Elements in groups 6 and 7 periodic tables are most likely to be attracted by one or two other electrons.

In order to attract another electron into orbit around the core, the atom must release energy. The rate of this energy is written as a negative number because the atom emits energy and therefore has an energy loss network. Atoms that emit less energy in attracting another electron are said to have lower electron affinity and are more likely to lose additional electrons.

Electron affinity is lower in atoms with greater molecular weight. Part of the reason is that heavier atoms naturally contain more electrons for balance with the number of protons in the core. With many electrons orbiting atomic core, free electron has a better chance of discouraging the atom.

Extra electrons are pulled into the farthest electron orbit in the atom. The greater distance of the external orbital in atoms with a greater molecular weight does not have the effect on the ability of the atom to attract these electrons, although atoms of a larger molecular weight have a lower scale of electrons affinity. All atoms in Group 7 give an attraction +7, regardless of the number of electrons already in orbit. Similarly, all atoms in Group 6 give the attraction +6. This is because the electron is attracted by the number of protons in the core minus the number of electrons on all lower orbitals.

oxygen and sulfur are able to attract two other electrons into their orbit. This is unusual because a negatively charged atom requires a large amount of energy to attract addiv inner negative particles. These elements have high electrons affinity and are the only two elements that are known to exist with a -2 hub.

Atom is composed of positive and negatively charged particles and particles that do not have a charge. The core of the atom contains protons that have a positive charge and neutrons that do not have a charge. The number of protons in the atom is equal to the atomic number of the atom, which means that each atom of the same type contains the same number of protons. Individual atoms may have more or less neutrons or electrons than each other, although most atoms maintain the balance of positive and negative particles.
