Question 10

Atoms with different number of electrons are called…

Answer 10

ions

Question 11

Two or more elements bonded together is…

Answer 11

compound

Question 12

covalent bond

Answer 12

bonds between 2 non-metals

Answer 13

-strongest chemical bond
-results from sharing electrons to fill outer electron shell

Question 14

Polar molecules

Answer 14

-unequal sharing of electrons, which creates unequal charges on each sides of an element.

Question 15

Non-Polar molecules

Answer 15

-Equal sharing of molecules which creates noc harge on an element

Question 16

Ionic bonds…

Answer 16

bonds between metal and non-metals. Created by gaining or losing electrons.

Question 17

When dissolved in ______ ions are created

Answer 17

water

Question 18

Cations

Answer 18

ions that possess a positive charge; it has more protons than electrons because the atom loses electrons

Question 19

Anions

Answer 19

ions that possess a negative charge; it has more electrons that protons because the atom gains electrons.

Question 19

fairly weak bonds-formed from polar covalent compounds that have a partially positive hydrogen attracted to a partially negative “substance”-usually oxygen

Answer 19

Hydrogen bonds

Question 20

These bonds are responsible for many of water’s properties
