Question 1

Structure of an atom

Answer 1

what gives an element its chemical and physical properties
atoms are made up of three smaller particles

Question 2

electrons

Answer 2

negatively charged particles that spin around the positive centre of the atom in circles energy levels. Their mass it is nearly zero

Question 3

Protons

Answer 3

positively charged particles that are contained in the nucleas of the atom they have a mass of 1 amu

Question 4

Neutrons

Answer 4

Particles with no charge that are also contained in the necleus of the atoms, mass of 1 amu

Question 5

Atomic numbers

Answer 5

the atomic number of an element tell us how many protons that the element has.
(bottom number)

Question 6

electron arrangement

Answer 6

the first energy level can hold a maximum of 2 electron, others up to 8 electron

Question 7

Mass number

Answer 7

the mass number is given at the top left of the element symbol

Question 8

isotopes

Answer 8

isotopes are atoms with the same atomic number but different mass. same number of protons but a different number of nuetrons
