Explanation:
In a magnetic field, the radius of the charged particle is as follows.
r =
where, m = mass, v = velocity
q = charge, B = magnetic field
Therefore, q will be calculated as follows.
q =
=
=
=
= +2e
Thus, we can conclude that the charge of the ionized atom is +2e.
Answer: protons and neutrons.
The nucleus is made up of 3 subatomic particles that are protons,neutrons and electrons.
General notation of an element is
where, X is the Element, A is the Atomic Mass and Z is the Atomic Number
If we know the number of protons we can easily find out the atomic number of any element because Atomic Number = Number of protons in an element.
And in addition if we know the number of neutrons we can easily find out the atomic mass of an element because
Atomic Mass = (Number of protons) + (Number of neutrons)
If we get to know the atomic number and atomic mass, we can easily tell what element is it by looking from the periodic table.
