What is ionization energy?

Answer 1

Briefly, it is the energy required to completely remove a valence (outer shell) electron from its atom when forming an ionic bond.

Answer 2

Ionization energy is the amount of energy required to remove an electron from an atom or molecule, turning it into a positively charged ion. The higher the ionization energy, the more difficult it is to remove an electron. It is a key factor in determining the reactivity and chemical properties of an element.

Answer 3

The ionised energy is the amount of energy it takes to detach one electron from a neutral atom, thus it meaures how strong the otermost electron is attached to the atom. First Ionised Energy: Na -> Na+ + e-

Answer 4

Since electrons are attracted to an atomic nucleus (due to opposite charges), it requires energy to pull an electron away from an atom; the energy used to do so is called the ionization energy, since an atom becomes an ion, when it loses an electron.

Answer 5

The energy it takes to remove a valence electron from an element.

Answer 6

the first ionization energy of an element is the amount of energy needed to remove one electron from each atom in a mole of atoms in the gaseous state.

Answer 7

first ionisation energy is defined as the energy required for removing of one electron from outer shell is called first ionisation energy(IP1)

Answer 8

Ionization energy refers to the energy needed to remove electrons from an atom

Answer 9

.The energy required to remove an electron from an atom

Answer 10

The energy required for an element to ionize
