Ionic bonds form between what classes of elements?
Metals and nonmetals.
Water is made with oxygen and is bonded to another element with covalent bonds. What is the other element and how many atoms of that element is needed?
Hydrogen and two atoms of hydrogen are needed.
What does an atom have to do to become a positive ion?
Lose an electron.
How do the electrons move in metallic bonds?
They move around freely.
Which element is more electronegative; Cl or F?
F
How do the elements K and F bond?
K (Potassium) loses an electron while F (Fluorine) gains an electron.
When does a covalent bond form?
Covalent bonds are formed when atoms share electrons.
What does an atom have to do to become a negatively charged ion?
Gain an electron.
List 3 properties of metals.

What are the qualities of the substances that are bonded by ionic bonds?
They are hard, brittle, and have high melting points.
What are the qualities of a substance that is bonded by covalent bonds?
Low melting point and low boiling point, also brittle and solid state.
Would two positive ions make bonds? Why?
No, because the same charges are not attracted to each other.
Metals are malleable which means?
Metals can be hammered into sheets.
Why don't elements in Group 18 make bonds?
Group 18 elements have a full octet.
