1. Radium has 88 protons.
2. Radium has not... americium !
In any neutral atom, the number of protons in it is equal to the number of electrons in it. A radium atom has 88 protons and electrons.
Not sure about portons but americium has 95 protons.
The atomic number of the element americium (Am) is 95. From this we can tell that the nucleus of the atom is 95 protons. As an atom is electrically neutral (number of positively charged protons is equal to the number of negatively charged electrons and both carry a relative charge of magnitude 1), an americium atom would also have a total of 95 electrons in its electron shells. The mass number of Am is likely around 243, so you can estimate that an atom of Am would have 243 - 95 = 148 neutrons. Of course, if there are isotopes, the number of neutrons would vary for each isotope of americium.
Radium 226 has 88 protons, 88 neutrons, and 138 electrons.
Americium has 95 protons.
Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number of protons

Americium-241 has: 95 protons, 95 electrons, 146 neutrons.For other isotopes the number of neutrons is different.Number of neutrons = Mass number of an isotope - 95
Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number of protons
Radium has 88 protons. The atomic mass of the most stable radium isotope - 226Ra - is 226,025 409 8(25).
