Atoms and Elements

Question 1

what is a proton and where is it found?

Answer 1

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

Question 2

what is a neutron and where is it found?

Answer 2

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

Question 3

what is an electron and where is it found?

Answer 3

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

Question 4

what charge do atoms have?

Answer 4

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

Question 5

what is the mass number in the periodic table?

Answer 5

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

Question 6

what is the atomic number in the periodic table?

Answer 6

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

Question 7

what are the number of electrons in the shells?

Answer 7

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

Question 8

what are compounds?

Answer 8

Compounds are two or more different atoms chemically bonded together

Question 9

what is ionic bonding?

Answer 9

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

Question 10

what is covalent bonding?

Answer 10

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