How many protons does radium have?

Radium has 88 protons.

1. Radium has 88 protons. 2. Radium has not... americium !

Radium has 88 protons and 138 neutrons.

There are 88 protons/electrons in radium. There are 138 neutrons.

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.

Radium has 88 protons. The atomic mass of the most stable radium isotope - 226Ra - is 226,025 409 8(25).

There is no such atom as Radium 87 - it is Radium 88 and thus has 88. Francium is 87.

Radium has 88 protons, radon has only 86 protons.

Radium element is in the s block. It has 88 protons in a single atom.

The isotope of radioactive radium with the longest half-life is radium-226. Radium-226 has a mass number of 226 with 88 protons and 138 neutrons.

Radium has 88 protons.

22088Ra, like all isotopes of radium, has 88 protons.

Radium 226 has 88 protons, 88 neutrons, and 138 electrons.

The atomic number of radium is 88. So there are 88 protons and 88 electrons. In Ra-222, there are 134 neutrons (222 - 88 = 134).

The atomic number of radium (Ra) is 88. So there are 88 protons

Radium has 88 protons. Number of neutrons = Atomic mass of an isotope - 88 For example, the best known isotope of radium, 226Ra, has 138 neutrons.

All isotopes of radium have the same number of protons; the number of neutrons is different.

Radium. I think.

Because the atomic number of radium is 88, radium has 88 protons. The number of neutrons is different for each isotope: Number of neutrons = Atomic mass of an isotope - 88 For example radium 226 has 138 neutrons.

Radium has 88 protons and 88 electrons. Number of neutrons = Atomic mass of an isotope - 88 For example, the best known isotope of radium, 226Ra, has 138 neutrons.

The number of protons of an atom is given by its atomic number. Checking the periodic table, we see that the atom with 88 protons is radium. The isotope of radium with 138 neutrons would thus be 226Ra.

Radium has 88 protons, and therefore 88 neutrons. Together 176 particles is too many to fit into a diagram easily. I've done a seach on the Internet and can not find a diagram for the inner structure of Radium but have found a good electron diagram, if that is any help? It is here: [http://upload.wikimedia.org/wikipedia/commons/thumb/1/13/Electron_shell_088_Radium.svg/558px-Electron_shell_088_Radium.svg.png Radium (WikiCommons)]

Radium's atomic number is 88. Thus, it has 88 protons. Therefore, 228Ra has 228 - 88 = 140 neutrons.

The atomic mass is 226, and the number of protons is 88. Subtract the atomic mass from the number of protons. 226-88= 138 neutrons

Radium (not to be confused with radon)

It may be possible to bombard Radium 15 with protons, creating Radium 16. Radium 16 has a fast decay rate. This would release large amounts of energy.

Hydrogen atom has 1 proton and 1 electron; radium has 88 protons and electrons. Also radium is radioactive.

The neutrons aren't really relevant, since we don't know what the mass of the radium nucleus was and the element is determined strictly by the number of protons anyway. Radium has an atomic number of 88; losing 4 protons would make the atomic number 84, which is polonium. (This is probably really a two-step process: radium -> radon -> polonium, where each step is an alpha decay.)

The 220 is the atomic MASS, which is the number of protons plus the number of neutrons. 88 is the atomic NUMBER, which is the number of protons only. The "Ra' is the abbreviation for radium, one of the first-detected radioactive elements.

It is an isotope of the element, radium (Ra), with 88 protons, 88 electrons and 147 neutrons (235 - 88 = 147).

This is the isotope radium-226.

Radium - 228.

When 226radium undergoes alpha decay it becomes 222radon. Note that an alpha particle is composed of two protons and two neutrons. Note also that that the alpha particle is also a helium-4 nucleus. There are 4 nucleons (protons or neutrons) in the alpha particle (or helium-4 nucleus). If we look at 226radium and subtract 4 from the 226, we get 222. The 4 comes from the total number of protons and neutrons in the alpha…

The atomic mass is 226 (for the isotope 226Ra), and the number of protons is 88. Subtract the atomic mass from the number of protons. 226-88= 138 neutrons. As a general rule, for all the isotopes of all chemical elements: Number of neutrons = Atomic mass - Number of protons (Atomic number)

Radium has 88 electrons.

Radium has seven electron shells; the valence of radium is 2+.

There are 2 valence electrons in Radium. There are 2 valence electrons in Radium.

Radium has 86 electrons.

The radioactive gas radon (Rn).

No. Radium is a heavy metal, atomic number 88 (with 88 protons). An alpha particle is a helium nucleus, atomic number 2. Radium decays by each atom emitting an alpha particle, becoming Radon gas, atomic nubmer 86.
