Ionic/Covalent/Metallic Bonds Part 1

Why do all bonds form?

• To fill up the outer shell and become more stable.

• To look cool.

• To become less stable.

• So they don't have to be alone.

What two types of atoms make a covalent bond?

• metal atom and metal atom

• metal atom and non metal non atom

• non metal atom and non metal atom

Atoms are most stable when their outer shell is full or complete.

• True

• False

What part of an atom is involved in chemical bonding?

• proton

• neutron

• electron

A metallic bond is a bond between ________.

• nonmetals

• metals

• transition metals

• metalloids

Which of the following is NOT a property of metals?

• Hard

• Can conduct electricity

• Very brittle (breaks easily)

• Malleable (can bend without breaking)

What do electrons do in a metallic bond?

• They stay on the metal atom.

• They are transferred from atom to atom.

• They form a covalent bond with another atom.

• They float around freely.

What is meant by the term "sea of electrons"?

• It's what we call all the free floating electrons in a metal.

• It's what we call electrons that are floating in a liquid.

• It's the total number of electrons in a metal atom.

• It's the total number of electrons in the ocean.

Why do all bonds form?

• so the number of protons equals the number of electrons

• so an atom can become unstable

• to fill the outermost energy level

Valence electrons are found

• in the innermost energy level of an atom

• in the middle energy levels of an atom

• in the outermost energy levels of an atom
