Atomic Structure

Question 1

Scientists discovered a neutral particle inside the nucleus. Give the name for this Particle

Answer 1

Neutron

Question 2

how the Dalton model of an atom has changed over time because of the discovery of subatomic particles

Answer 2

he showed that electrons occupy shells or energy levels around the nucleus.

Question 3

Recall the relative charge and relative mass of:
Proton
Neutron
Electron

Answer 3

Proton: Mass: 1 - Charge: +1
Electron: Mass: 0.0005 - Charge: -1
Neutron: Mass 1 - Charge: 0

Question 4

Explain why atoms contain equal numbers of protons and electrons

Answer 4

Because Protons are positively charged and electrons are negatively charged so they cancel out for form 0

Question 5

Recall the meaning of the term mass number of an atom

Answer 5

Total Number of Protons and Neutrons

Question 6

Explain how the electronic configuration of an element is related to its position in the periodic table

Answer 6

the number of electrons in the outermost shell of an element is represented in the periodic table as the group number that element is situated in
