50
Q

What happens if the number of neutrons changes?

A

An isotope is formed

51
Q

What happens if the number of electrons changes?

A

A ion is formed.

52
Q

Compounds

A

Substances made of 2 or more elements.

53
Q

H20

A

Water

54
Q

A

Salt

55
Q

Chemical bonds

A

Force that holds substances together.

56
Q

Forming Chemical bonds creates……

A

Energy

57
Q

Breaking chemical bonds releases….

A

Energy

58
Q

Ionic Bond

A

A bond formed between 2 ions

59
Q

Ions

A

Atoms that have lost or gained electrons.

60
Q

To make Negative ions what was gained?

A

Electrons

61
Q

To make positive ions what was lost?

A

Electrons

62
Q

How is a compound different from the things that make it?

A

Elements make a compound. they are two different elements that come together to make the compound.

63
Q

What are the small parts that make up an atom?

A

Protons, neutrons, electrons

64
Q

Why are isotopes of an element still the same in how they act in chemistry?

A

They are gaining and losing neutrons. Which are neutral so it will only affect the mass and not balance. Because neutrons are neutral. They are neither proton or electron.

65
Q

What’s the difference between two types of bonds: ionic and covalent? (Hint: how do atoms share or give away their electrons?)

A

Ionic gives or takes electrons. Covalent bonds shares electrons.
