Question 1

Valence

Answer 1

Capacity of the atoms of an element to form chemical bonds

Question 2

Electrostatic potential energy (Eel)

Answer 2

The energy a charged particle has because of its position, relative to another charged particle, Eel is directly proportional to the product of the charges of the particles and inversely proportional to the distance between them

Question 3

Ionic bond

Answer 3

Bond resulting from the electrostatic of the attraction to a cation to anion

Question 4

Lattice energy

Answer 4

Energy released when one mole of an ionic compound forms from its free ion in the gas phase

Question 5

Crystal lattice

Answer 5

An ordered three dimensional array of particles.

Question 6

Covalent bond

Answer 6

A bond created by two atoms sharing one or more pair of electrons

Question 7

Bond length

Answer 7

Distance between the nuclei of two atoms joined in a bond

Question 8

Bond energy

Answer 8

Energy needed to break one mole of a specific covalent bond in the gas phase
