Question

List 2 similarities and 2 differences between the isotopes.Indícate 2 things that are similar (or the same) between the isotopes.Indícate 2 things that are different between the isotopes.For silicon

Answer 1

1) Isotopes. Two atoms that have the same number of protons but a different number of neutrons.

2) Isotopes of Silicon.

`_(14)^(28)Si`

Mass number: 28

Atomic number: 14

Electrons: 14

Neutrons = mass number - atomic number = 14

`_(14)^(29)Si`

Mass number: 29

Atomic number: 14

Electrons: 14

Neutrons = mass number - atomic number = 15

3) Similarities and differences

These two isotopes of Silicon have the same number of protons and electrons.

14 protons and 14 electrons

These two isotopes of Silicon have different mass numbers and neutrons.

The first one, mass number 28 and 14 neutrons.

The second one, mass number 29 and 15 neutrons.
