1

Atoms are...

the smallest particle of matter

2

Every atom is made up of ____ different types of particles

3

3

In the nucleus there are ____ and _____

Protons, neutrons

4

Protons are positively charged, negatively charged, or uncharged ?

Positively charged

5

Neutrons are positively charged, negatively charged, or uncharged ?

uncharged

6

Flying around the nucleus are _____

electrons

7

Electrons are positively charged, negatively charged, or uncharged ?

negatively charged

8

The atomic number of an element is _____

the amount of protons

9

The atomic mass of an atom is the number of...

protons + neutrons

10

Do electrons have a mass?

No, they are so small that they effectively have no mass so we do not include them in the atomic mass

11

What are ions?

Ions are atoms that have lost or gained electrons

12

If you gain or lose _____ it affects the overall electrical charge of an atom.

electrons

13

Are ions naturally electrically charged?

Yes

14

An isotope of an element is ....

a variation of that element that has a different number of neutrons

15

Does an isotope change an atoms atomic mass?

Yes, because the number of neutrons is different, and neutrons carry mass

16

an example of an isotope is?

Carbon-12 to Carbon-13

Carbon-12 is the most common type of carbon, which has 6 protons and 6 neutrons. If a carbon atom forms that has an extra neutron then that is called Carbon-13.

17

Carbon-12 has ____ protons and ____ neutrons

6 and 6

18

Is Carbon- 12 the most common type of carbon?

Yes

19

Why is carbon-13 an isotope of Carbon-12?

Because the Carbon atom carries one more neutron, and thus has a larger mass.

20

What can Isotopes be used for?

to determine how old things are

21

Is Carbon-14 used to date archeological materials?

Yes

22

When two or more atoms become linked together, that is called...

chemical bonding

23

Chemical bonding is when ____ or more atoms ____ together.

2, link

24

After two or more atoms are chemically bonded, the resulting arrangement of atoms is called a...

molecule

25

what is a molecule?

a group of atoms bonded together

26

What are two different ways/processes of chemical bonding?

ionic bonding and covalent bonding

27

An ionic bond happens when

an atom that has a very strong positive charge in its nucleus attracts electrons from other atoms. The atom that steals an electron will become negatively charged, and the atom that loses an electron will become positively charged. Consequently, they will be stuck together because of their opposite charges like a magnet.

28

if you have an atom that steals an electron from another atom, the thief atom will become _______ charged and the victim atom will become ______ charged.

negatively, positively

29

In a covalent bond the two atoms _____ electrons.

share

30

What is a covalent bond?

When two atoms share electrons in a giant electrons cloud.
