Bonding

100

What is the part of the atom that has to do with how atoms bond?

Valence electrons

200

What is the only element that has a full valence shell, but doesnt have 8 valence electrons?

Helium

300

What is the difference between Ionic and Covalent bonding?

Covalent bonds share electrons, Ionic is an transferring of electrons.

400

Which is stronger: an Ionic or a Covalent bond? WHY?

Ionic because the transferring of electrons creates a higher attraction of electrons, strengthening the bond.

500

What type of elements form a Covalent bond? Give an example of a covalent bond

Nonmetals- ex. water (H2O), hydrogen gas (H2), chlorine gas (Cl2), ammonia (NH3), methane (CH4), carbon dioxide (CO2)
