Atomic structure

Question 1

Relative mass and relative charge

Answer 1

Protons: 1 +1
Neutrons; 1 0
Electrons: 1/1840 -1

Question 2

Electrons

Answer 2

Is around the atom has negligible mass therefore moves rapidly

Question 3

Proton/atomic number

Answer 3

Number of protons/electrons in an atom

Question 4

The nucleon/mass number

Answer 4

Is the total number of protons and neutron in an atom, we can subtract that with the proton number to get the the number of neutrons.

Question 5

Isotopes

Answer 5

Isotopes are the atom of the same element with the same number of protons/electrons but has different number of neutrons

Question 6

Isotopes chemical properties

Answer 6

Isotopes have the same chemical properties as they have the same number of electrons which are involved in chemical reaction

Question 7

Isotopes chemical properties

Answer 7

Isotopes have the same chemical properties as they have the same number of electrons which are involved in chemical reaction

Question 8

Isotopes physical properties

Answer 8

Isotopes have t different physical properties as they have different relative atomic masses

Question 9

Valence electrons

Answer 9

The chemical properties is dependent
