Answer 2

Answer:

VALENCY

valency is ‘the maximum number of univalent atoms (originally Hydrogen or Chlorine atoms) that may combine with an atom of the element under consideration, or with a fragment, or for which an atom of this element can be substituted’. It is important to note the fact that univalent atoms are considered here, as they would pair up with one electron at a time. However, if an element like Oxygen, which is a divalent atom, is used for this purpose, the valency will be equal to double the amount of Oxygen that took part in the formation of bonds.

ION

Ions are atoms with extra electrons or missing electrons. When an atom's outermost orbital gains or loses electrons (also known as valence electrons), the atom forms an ion. An ion with more protons than electrons carries a net positive charge and is called a cation. An ion with more electrons than protons carries a net negative charge and is called an anion. The number of neutrons doesn't come into play since they are electrically neutral. Changing the number of neutrons determines the isotope.
