Bonding Intro - Ionic

How can you use the periodic table to determine valence electrons

• You can use the period number on the left

• You can use the atomic mass in the box

• You can use the group number at the top

• Nonmetal and metal

• Nonmetal and nonmetal

Sodium chloride is held together by an ionic bond of a metal and a nonmetal. Which atom is the metal?

• Sodium

• chlorine

During and ionic bond which of the following is true?

• The sodium (Na) atom becomes negatively charged and the chlorine atom (Cl) becomes positively charged.

• The chlorine (Cl) atom becomes negatively charged and the sodium atom (Na) becomes positively charged.

What holds the ionic bond together?

• Opposite charges on the ions

• Similar charges on the ions

• Spit

• The electrons are shared and travel around both nuclei

What rule has to be completed for all atoms to be stable and happy- has something to do with 8 valence electrons

• Ionic bond rule

• Octet rule

• Octopus rule

• Ion rule

What do we call an atom that gains a charge?

• Ions

• the atomic number changes

• isotopes
