A transfer of charge is actually a gross movement of electrons. Charged objects have a normal or "balanced" state. This state is balanced in a sense of positive charges (protons) and negative charges (electrons). When an object has an excess of deficiency of electrons, it will try to regain its balance by releasing or accepting electrons.
Answer:
Is the mass number
Explanation:
Every atom is usually identified by using two different numbers:
- Atomic number: generally labelled with Z, corresponds to the number of protons in the nucleus, so Z = p
- Mass number: generally labelled with A, corresponds to the number of protons+neutrons in the nucleus, so A = p + n
To find the number of neutrons in a nucleus, therefore, we can do
n = A - Z
Answer:
yes it's a matter of probability
