Earth Science Ch.4 Review: Chemical Bonds

What type of bond is formed when atoms share electrons?

An electron dot diagram uses an element's symbol and dots to show:

What elements and how many atoms of each make up water?

What outer level electron patterns are found in the periodic table?

Which 2 groups of elements are likely to combine to form ionic salts?

Which element does NOT follow the rule for determining the # of outer level electrons?

What makes an ion negative?

An atom that has gained or lost electrons:

What particle of an atom determines how actively the atom will combine with other atoms?

What makes an atom stable?

A neutral particle formed when atoms share electrons:

How many electrons can the second energy level of an atom hold?

An atom that loses an electron has what type of charge?

The same type of atom shares its electrons evenly in a:

A pure substance make of 2 or more elements:

What group of elements is most likely to combine with other atoms?

What makes up a Chemical Formula?

This group of elements is least likely to combine with other atoms:

What type of bond involves 2 pair of covalent bonds?

When one of the atoms attracts the electron more strongly and shares them a little unequally:

What type of bond is held together by positive and negative ions?

What is the formula for finding the number of electrons in an outer energy level?
