Answer:

F - Cl - Br - I - At - Ts

Explanation:

All the halogens, are the elements that forms a ion with a -1 charge.

The elements from group 17 in the Periodic Table are the one that has 7 electrons of valence. They need only 1 e⁻ to have the closest noble gas conformation so, they can comply with the octet rule.

This is an example:

Cl₂ (g) + 2e⁻ → 2Cl⁻

Chlorine which is a diatomic gas, gains 2 electrons to make 2 moles of chloride (in order to the balance the reaction)

Answer:

Explanation:

1. Force between two charged ions: Electrical force

Electrical force of attraction exists between two charged ions due to constant flow of electrons occuring within their field of influence.

2. Ion made of two or more atoms of different elements : Polyatomic ion

A polyatomic ion is made up of two or more different elements. Most radicals forms polyatomic ion e.g SO₄²⁻

3. Compound whose atoms form bonds by transferring electrons : Ionic compound

Ionic compounds forms by the transfer of electrons from a less electronegativbe atom to a more electronegative one. This is in a bid for the atoms to achieve stability.

4. Smooth solid formed by repeating patterns of ions, atoms, or molecules

: Crystal

A crystal is a unit of an atom which is made up of definite repeating patterns over a long range.

5. Chemical bond formed when electrons are transferred: Ionic bonds

The bonds resulting from the transfer of electrons between two atoms is an ionic bond. An example is that between Na⁺ ions and Cl⁻ ioin in NaCl
