Could you help me with two Physics problems?

Question

1) Which of the following particles has almost no mass?

A. Proton

B. Neutron

C. Electron

2) An atom has no electrical charge because _____.

A) the number of protons is equal to the number of neutrons

B) the number of neutrons is equal to the number of electrons

C) the number of protons is equal to the number of electrons

Answer 1

1)C

2)C

Answer 2

1 is pretty stupid. The mass of an electron is about 1/1850th of the mass of the proton (and neutron is pretty similar), but it's not almost no mass!

2: protons are positive, neutrons are neutral. Electrons are negative. So it must be ....

Answer 3

c. it has been proved that it weighs the less almost 0 but proton and neutron weigh about 1

because the number of electrons and protons are the same which means there are as much as + charges as there are - s(normally)

c.

Answer 4

1 - electron

2 - No. of protons =No. of electrons
