ASAP Two different atoms have four protons each and the same mass. However, one has a negative charge while the other is neutral. Describe what each atomic structure
could be, listing the possible number and location of all subatomic particles.

Explanation:

Just a little fundamental knowledge:

   Protons are positively charged particles

   Neutrons do not carry any charges

  Both protons and neutrons are located in the nucleus of an atom. They determine the mass of any atom.

 Atoms having the same mass will have the same number of protons and neutrons. Collectively, the number is called mass number.

 Electrons are negatively charged particles orbiting round the nucleus of an atom. They take up the the bulk volume of the atom. They do not add to the weight of an atom.

The protons, neutrons and electrons are the three fundamental particles in an atom.

Two given atoms:

    A = 4 protons and negatively charge

    B = 4 protons and neutral

Location:

Possible number of subatomic particles:

For atom A;

     Protons  = 4

     Electrons  = 4

    Neutrons  cannot be determined.

Note: in a neutral atom, the number of protons and electrons are the same

For atom B:

    Protons = 4

    Electrons = 4 + x where x is the number of electrons gained

    Neutrons  cannot be determined.

When an atom becomes charged, it has lost or gained electrons. A negative charge depicts an atom the has gained additional electrons.

The value of x, is always a positive integer greater than 0 and less than 7

   Electrons can be 5, 6, 7, 8, 9 or 10

When the number of electrons reaches 10, the atom is stable.

there are two significant figures.
