Complete the following table for the three key subatomic particles.
ASHA 777 [7]

Answer:

This question is incomplete without the table

Explanation:

The missing table is attached to this answer.

There are three subatomic particles found in an atom; protons, neutrons and electrons. The properties of the subatomic particles will be classified under the following subheadings (which are the empty columns/boxes in the attachment)

SYMBOL

The symbol of proton is "p⁺", the symbol of neutron is "n⁰" and the symbol of electron is "e⁻".

CHARGE

Looking at the symbol of the subatomic particles, one can guess the charge of each of the particles from the superscript.

Protons are positively charged, electrons are negatively charged while neutrons have no charge/electrically neutral.

The relative charge of proton is +1 while it's absolute charge is +1.60218 × 10⁻¹⁹

The charge of a proton was first determined by Ernest Rutherford using the gold-foil experiment

The relative charge of electron is -1 while it's absolute charge is -1.60218 × 10⁻¹⁹

The charge of an electron was first determined by R. Milikan using the oil-drop experiment

The relative charge and absolute charge of neutron is 0

The charge of a neutron was first determined by (or credited to) James Chadwick.

MASS

The relative mass (amu) of proton is 1.00727 while that of neutron is 1.00866. The relative mass (amu) of an electron is 0.00054858 while it's absolute mass (g) is 9.10939 × 10⁻²⁴.

The mass of an electron was first measured by J. J. Thomson.

The mass of a proton was first measured by (or credited to) Ernest Rutherford.

The mass of a neutron was first measured by James Chadwick.

LOCATION

The protons and neutrons <u>are located inside the nucleus</u> which is found in the centre of an atom while the electron(s)<u> is/are found outside the nucleus but within the atom</u>.
