【How is an atomic nucleus?】

《Things which form the atomic nucleus.》

An atom is made up of electrons and the atomic nucleus,and the atomic nucleus is also composed of various things.😃

Roughly speaking,its main constituent elements are a proton and neutron.Both of weight are almost same,and we express it like the next.The atom's amount of mass is 1.😃

However,the proton is different form the neutron in relation to electric charge.While the proton's electric charge is ＋1,the neutron doesn't have electric charge in the least.It's neutral electrically.😚

《An atomic number Z and amount of mass A》

We call a number of the protons which form the atomic nucleus an atomic number.If being the atom of which atomic number is Z,the atom charges with ＋ Z electrically.

I want to say that その原子は電気的に＋Zに荷電している,but there isn't any appropriate examples.I'm wondering if my English is correct.😂

The atom has the same number electrons as its atomic number,and the electrons form cloud,so the atom is neutral electrically.💡
