1
Q

what is a proton and where is it found?

A

Protons are positively charged and have a mass number of one and is found within the nucleus

2
Q

what is a neutron and where is it found?

A

Neutrons are neutral as they have no charge and have a mass number of one and is found in the nucleus

3
Q

what is an electron and where is it found?

A

Electrons are negatively charged and have a mass number of less than one, unlike protons and neutrons electrons are found within the shells of an atom

4
Q

what charge do atoms have?

A

Atoms have no charge/neutral until they gain or lose electrons

5
Q

what is the mass number in the periodic table?

A

The mass number is the top number and tells us the amount of protons and neutrons

6
Q

what is the atomic number in the periodic table?

A

The atomic number is the bottom number and tells us the number of protons and electrons

7
Q

what are the number of electrons in the shells?

A

1st shell = 2
2nd shell = 8
3rd shell = 8

8
Q

what are compounds?

A

Compounds are two or more different atoms chemically bonded together

9
Q

what is ionic bonding?

A

Ionic bonding is the process where an atom gains or loses an electron to get a full outer shell

10
Q

what is covalent bonding?

A

Covalent bonding is the sharing of electrons between two or more atoms to get a full outer shell
