Ionic Bonds

Why do atoms give or take electrons?

• To increase their atomic mass

• To have a maximum number of outer (Valence) electrons

• To Decrease the number of Protons

• To get rid of all of their electrons

The first energy level holds 2 maximum electrons. How many does the second level hold?

• 2

• 4

• 6

• 8

A chemical bond that forms when valence electrons are transferred from one atom to another

• Ionic

• Covalent

• Molecular

• James

A charged particle that forms when an atom gains or loses an electron is called

Name the ionic compound made of sodium and fluorine

• Fluorine Sodiumide

• Sodium Fluoride

What is the charge of a Beryllium Ion?

(Beryllium is in group 2)

• +2

• -2

• +8

• 0

What do the green and purple circles represent?

• Two different noble gasses

• protons and electrons

• two different types of neutral atoms

• positive and negative ions

Why do ionic substances form this crystal lattice shape?

• heat and pressure shape them

• the electrical energy zaps them into place

• the opposite charges attract each other forming the pattern

• Ions do not form shapes like this. This is a trick question
