Question

A negative ion is an atom that_______ electron?

Answer 1

Hint: We know Ions, any iota or gathering of iotas that bears at least one sure or negative electrical charge. Emphatically charged ions are called cations; contrarily charged ions, anions. Ions are framed by the expansion of electrons to, or the expulsion of electrons from, nonpartisan iotas or ions or different ions; by mix of ions with different ions; or by crack of a covalent connection between two molecules so that both of the electrons of the bond are left in relationship with one of the previously reinforced iotas. Instances of these cycles incorporate the response of a sodium ion with chlorine ions to frame a sodium cation and a chloride anion; the expansion of a hydrogen cation to a smelling salts atom to shape an ammonium cation; and the separation of water ions to shape a hydrogen cation and a hydroxide anion.

Complete answer:
As we know that a negative ion is an iota that has acquired at least one electron. Anions are contrarily charged ions. They are framed when non-metal acquires the electrons. They acquire at least one more than one electron and don't lose any protons. In this way, they have a net negative charge. A few instances of anions are Iodide, chlorine, hydroxide.

Note:
We need to know that ions which are a piece of the science subject Chemistry structures from molecules and electrons that have either acquired or lost their weight by the expulsion or adding of at least one valence electrons which would make either sure or a negative charge. Anions are the ions with a negative charge and the ones with a positive charge are called cations. Since the two of them have charges of contradicting characteristics, they get drawn to each other and in this manner framing an ionic connection between them.
