P + and e -
As the charges are balanced in this atom the atom is neutral.
The number of protons can not be changed in an atom, while the number of electrons can be.
Generally an atom contains similar number of electrons and protons. That is why an atom is neutral.
A neutral atom of a chemical element has a constant number of protons and electrons; loss or gain of electrons transform this atom in an ion.After the change of the number of protons the identity of the atom is lost.
If neutrons, electrons, and protons leave the atom, the charge on the atom will change based on the number of protons and electrons that have left. Protons and electrons have opposite charges, so if electrons leave, the atom becomes positively charged, and if protons leave, the atom becomes negatively charged. Neutrons do not affect the charge of the atom since they are neutral.
The atom in a normal state would have two protons to match the two electrons, making the overall charge zero. If the atom is an ion, it would have an mismatched number of protons and electrons, giving it a positive or negative overall charge.
The neutral atom of cadmium has 48 electrons.
A neutral atom with 12 protons will have 12 electrons in order to balance the positive charge from the protons.
So the atom is neutral, if an atom had more protons than electrons, then the atom would have a positive charge, and if it had more electrons, then it would have a negative charge,if atoms had a charge, we would get shocked every time we touch something
It will have 30 protons and 30 electrons if the atom is neutral.
In any atom,there are protons, neutrons and electrons. As the name would suggest, neutrons carry no charge. Protons carry a positive charge and electrons carry a negative charge. So in an atom that has no charge there has to be an equal number of protons and electrons.
In a neutral atom, the number of electrons is equal to the number of protons. So, in an atom with three protons, it would contain three electrons. The number of neutrons does not affect the charge or number of electrons in the atom.
As you already know the atom consists of protons, neutron and eletrons. The number of protons determins which chemical element it is, and on the periodic table of elements, we can see that the next element after lithium is beryllium.-An atom with 3 protons, 3 neutrons, and 3 electrons.- An atom with 3 protons, 5 neutrons, and 3 electrons
