5 The negatively charged particles is called as?
1) Anion 2) Cation 3) radical 4) Atom
Answers
1) Anion
Explanation:
An anion is an ionic species having a negative charge. An anion has more electrons than protons, consequently giving it a net negative charge. For an anion to form, one or more electrons must be gained, typically pulled away from other atoms with a weaker affinity for them. The number of electrons gained, and so the charge of the ion, is indicated after the chemical symbol
Anions are one of the two types of ions. The other type is called a cation. A positively charged ion is known as cation. A cation is formed by the loss of one or more electrons by an atom or molecule.
Anions are attracted to the anode, while cations are attracted to the cathode.
The concept of an anion is important in the corrosion industry because certain anions facilitate corrosion.
E.g. chlorine (Cl) gains one electron to become Cl-.
