Which of the following particles has a negative charge? neutrino positron gamma ray all of the above none of the above

None of the above.

Explanation:

We have to find the  particle which have negative charge.

1.Neutrino

It has no negative charge.The charge on neutrino particle is zero.Therefore,It is neutral particle.

Hence,option A is false.

2.Positron

It has no negative charge.The charge on the particle is +1 e.Therefore, it is false.

3.Gamma ray

It is a from of electromagnetic radiation.It has charge 0.Therefore, it has no negative charge.

Hence, option 3 is false.

None of the above.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

the answer is a and have a great day
