Electron affinity is defined as the amount of energy emitted when an electron is added to a neutral atom in the gaseous state to form a negative ion. The energy of an atom is determined when the atom gains or loses energ... More »

In most atoms, electrons occupy a zone exterior to the nucleus. Though electrons are often represented as particles in discreet orbits around the nucleus, they cannot be said to occupy a specific point in space. Rather, ... More »

When an atom loses an electron, its overall charge becomes more positive by one. For example, a neutral atom would have a charge of positive one after losing an electron. More »

The ionization energy of an element is the amount of energy needed to rip an electron from an atom in the gaseous state. The ionization energy increases going up and to the right of the periodic table. More »

When an atom gains or loses an electron, it becomes an ion. Ions formed by the loss of an electron have a positive charge, and those formed by gaining an electron have a negative charge. More »

When an atom loses an electron, it becomes an ion. The loss of the electron leaves the atom with an additional positive charge and it becomes known as a cation. More »

An atom becomes a positive ion when it loses an electron, which is a negatively charged subatomic particle. Only metal atoms can become positive ions. More »
