Question

true or false: ionic bonding involves the shareing of electrons, oxide ions have a 2+ charge , electrons have a negative charge , a hydrogen molecule is held together by a strong covalent bond between two hydrogen atoms, a covalent bond is a shared pair of electrons.

Answer 1

1. False , shared electrons cause covalent bonds
2. False , they have 2- charge
3. True
4. True
5. Truw

Answer 2

Ionic bonding does not involve the sharing of electrons, that one is false. In ionic bonding, the metal's electrons are given to the non-metal, so that they're both like the nearest noble gas (full electron shells.) They are then drawn together because one has a negative charge (the non-metal) and one has a positive charge (the metal.)

Oxide ions have a 2+ charge: This is false, oxide ions have a 2- charge.

Electrons do have a negative charge, this is true.

Hydrogen molecule: pretty sure this is true. We know this because both atoms are non-metals.

The last one is true: a covalent bond is a shared pair of electrons between two atoms, however be aware that there can be more than one covalent bond between two molecules.
