Question

Which of the following statements about subatomic particles is FALSE? Which of the following statements about subatomic particles is FALSE? A neutral atom contains the same number of protons and electrons. Protons and electrons have opposite, but equal in magnitude, charges. Protons have about the same mass as electrons. Neutrons have no charge. Neutrons and protons are found in the nucleus of an atom.

Answer 1

Answer:

Protons have about the same mass as electrons is false

Explanation:

Electrons and protons have the same magnitude on charge but opposite sign

$e^{-}=-1.6\times10^{-19}C$: charge of electron

$e^{+}=1.6\times10^{-19}C$: charge of proton

Neutrons have no charge.

An atom is composed of protons and neutrons in the nucleus and electrons surrounding it, so a neutral atom has the same number of protons and electrons to has a net charge of zero. So, all the facts mentioned are true.

The false one is that protons have about the same mass as electrons, because the mass of an electron is $9.11\times10^{-31}kg$ and the mass of a proton is $1.67\times10^{-27}kg$ so the mass of a proton is a lot of bigger than electron mass.

Answer 2

Statement A, B, D and statement E are true about the protons, neutrons and electrons.

Charge on Electron, Proton and Neutron

An atom is the smallest unit into which matter can be divided without the release of electrically charged particles. These particles are protons, neutrons and electrons in the nucleus of the atom with electrons surrounding it. A neutral atom has the same number of protons and electrons to have a net charge of zero.

• Protons

Protons are positively charged particles that are present in the nucleus of all atoms. A proton is represented as “p”. The charge at the proton is $p = 1.6\times 10^{-19}\;\rm C$ and the mass is $1,67\times 10^{-27}\;\rm kg$.

• Neutron

Neutrons are present in the nucleus of all atoms except hydrogen. A neutron is represented as “n”. The mass of the neutron is considered equal to the mass of a proton. Neutrons are a type of subatomic particle with no charge i.e. they are neutral.

• Electron

Electrons are a type of subatomic particle with a negative charge. They are present in the outer shells within an atom and orbit the positively charged nucleus in well-defined orbits. An electron is represented as “e”. The electron has a charge of $e=-1.67\times 10^{-19}\;\rm C$. The mass of an electron is $9.11\times 10^{-31}\;\rm kg$.

Hence, from the above explanation, statement A, B, D and E are true about protons, electrons, and neutrons.
