Question

complete the table below, using the diagram of an atom shown at right. properties of subatomic particles name symbol charge (in multiples of e) approximate mass (amu) location on diagram electron ( e^{-} ) -1 select select neutron ( n^{0} ) 0 1.0 a proton ( p^{+} ) +1 select select

Explanation:

Step1: Recall electron mass

The approximate mass of an electron is 0.00054858 amu, which is so small that it is often approximated as 0 amu in basic atomic - structure discussions.

Step2: Determine electron location

Electrons are located in the electron - shells (orbitals) around the nucleus. In the given diagram, they are in the regions labeled B.

Step3: Recall proton mass

The approximate mass of a proton is 1.0 amu.

Step4: Determine proton location

Protons are located in the nucleus of the atom. In the given diagram, the nucleus is labeled A.

Answer:

name	symbol	charge (in multiples of e)	approximate mass (amu)	location on diagram
neutron	$n^0$	0	1.0	A
proton	$p^+$	+ 1	1.0	A
