Question

Complete the table below, using the diagram of an atom shown at right. Properties of subatomic particles name charge symbol (in multiples of e) approximate mass (amu) location diagram 1.0 electron O (choose one)

Answer 1

Dear student,

Name	symbol	charge ( in multiple of e)	approximate mass (amu)	Location on diagram
neutron	n	0	1.0	A
electron	e	-1	1/1837	B
proton	p	+1	1.0	A

Symbol:-

Protons are represented by small p.

Electrons are represented by small e.

Neutrons are represented by small n.
Charge:-

Protons are positively charged. Charge on is proton +1.

Electrons are negatively charged. Charge on electron is -1.

Neutrons are neutral , there is no charge on neutron.

Mass:-

Mass of proton is 1837 times the mass of electron.

Therefore comparative mass of electron is 1/ 1837 amu with respect to mass of proton i.e. 1 amu.

Mass of neutron is approximately equal to the mass of proton i.e.

1 amu.

Location:-

Protons and neutrons present in nucleus i.e at A on diagram.

While electrons revolve around the nucleus i.e. at B on diagram.

Please give positive rating to this answer.
