3ºA feb: Ionic compounds and lewis structure

How ionic bonds are made?

• As a result of attraction between neutrons and negative ions

• As a result of attraction between positive and negative ions

• As a result of attraction between electrons

• As a result of attraction between molecules

Which is the charge that ionic compounds has?

• Ions have unbalanced charges (More positive charges)

• Ions have balance charges

• Ions have unbalanced charges (More negative charges)

Why is it sodium chloride electrically neutral?

• Sodium has high electronegativity

• Because its a salt

• Each sodium balances the charge of one chloride ion

• Because its a ionic compound

Which are polyatomic ions?

• Ions made of infinite number of atoms

• Ions made of two atoms

• Ions made of a single atom

• Ions made of more than one atom

Positive charge ions are:

• Ions that gains electrons

• Ions that loses electrons

• Ions that gains protrons

• Ions that loses protrons

A ionic bond is the attraction between two oppositely charged ions?

• True

• False

the name of the positive ion (cation) comes first, followed by the name of the negative ion (anion) when given a chemical formula

• True
