Question 1

What is the relative charge and mass of protons, neutrons & electrons?

Answer 1

Charge:
Proton +1
Neutron 0
Electron -1

Mass:
Proton 1
Neutron 1
Electron 1/1840

Question 2

What is an ion

Answer 2

A charged atom

Question 3

What is an isotope

Answer 3

Atoms of the same element with different number of neutrons but same number of protons

Question 4

Will isotopes have the same chemical and physical properties?

Answer 4

They will have the same chemical properties because of the same electron configuration but different physical properties (e.g density,radioactivity,melting point) because of the different mass number

Question 5

What is the plum pudding model?

Answer 5

The atom is a ball of positive charge with negative electrons embedded in it

Question 6

What is the electron shell model?

Answer 6

The atom consists of a small, dense nucleus containing protons and neutrons with electrons orbiting around it in electron shells.
