Answer: electron–negative, neutron–neutral, proton–positive

Explanation:

Atom is made up of three subatomic particles named protons, neutrons and electrons. Both protons and neutrons are found inside the nucleus of the atom, while electrons are found outside the nucleus of the atom. The charge distribution are as follows:

- The proton carry a positive charge

- The neutron carry no electric charge (i.e electrically neutral)

- The electron carry a negative charge

Perform the following
Zarrin [17]

This problem is providing a mathematical expression which the result should be expressed with the correct significant figures. At the end, the result is 1209.0 because of the following:

<h3>Significant figures:</h3>

In science, the use of significant figures is crucial as long numbers are not necessarily required when reporting a numerical value, for that reason the importance of reporting measurements with the correct number of significant figures.

In the case of additions, we perform the normal operation as the first step:

1204.2 +4.79613 = 1208.99613

Next, we round the result to the least number of decimal places, in this case one because 1204.2 has just one decimal place, unlike the 4.79613 which has five, so that we round the 8 up to 9 and leave a 0 as the only decimal place:

1209.0
