What is radiums mass number?
The most stable isotope of radium - 226Ra - has the atomic mass 226,025 409 8 (25).
How many neutrons and electrons does radium have?
Radium has 88 electrons. The number of neutrons is different for each isotope: Number of neutrons = Atomic mass of an isotope - 88
How do you calculate protons neutrons isotopes for radium?
Atomic number of uranium: 92 (the same for all the isotopes) Atomic number of an element = number of protons = number of electrons Atomic mass of the isotopes of uranium: 234, 235, 236, 238, 239, 240, ...., etc. Atomoc mass - Atomic number = Number of neutrons
How many electrons and neutrons are in radium?
Radium has 88 electrons. The number of neutrons is different for each isotope: Number of neutrons = Atomic mass - 88 The most stable and known isotope of radium, 226Ra, has 138 neutrons.

The atomic mass of the radium isotope 226Ra is 226,025 409 8(25).
Mass number of radium?
The density of radium at about room temperature is 5.5  g·cm−3. That's 5.5 grams per cubic centimeter, or 5.5 grams per milliliter. A link to the Wikipedia article on radium is provided.
How many protons are present in radium also the and atomic mass of radium?
Radium has 88 protons. The atomic mass of the most stable radium isotope - 226Ra - is 226,025 409 8(25).
How many Nucleons are there in the radium isotope?
Radium has several isotopes, but the most common one is radium-226. This isotope has an atomic number of 88, indicating it has 88 protons. Since the mass number of radium-226 is 226, it contains a total of 226 nucleons, which includes both protons and neutrons. Therefore, radium-226 has 138 neutrons (226 - 88 = 138).
What is the mass of radium?
The atomic mass of radium is approximately 226 atomic mass units.
What is the number of atomicity of element radium?
Radium (Ra) has an atomic number of 88, which means it has 88 protons in its nucleus. In its neutral state, it also has 88 electrons. Radium is an alkaline earth metal and is known for its radioactivity. Its most stable isotope is radium-226.
What has 88 protons and 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.
