Helium is number 2 on the Periodic Table, and the number of its mass is 4. So, therefore it has 2 protons, 2 neutrons, and 2 electrons !
What else can I help you with?
What does the number 2 indicate in helium?
2 is the atomic number (or the number of protons) of helium.
What is the number of protons of helium?
Helium is number 2 on the Periodic Table, and the number of its mass is 4. So, therefore it has 2 protons, 2 neutrons, and 2 electrons !
Which noble gas has the least number of protons?
Radon (as down a group, the atomic size increases and the ionization energy decreases)
What is the number of protons in helium?
2
How many protons are there in heliume?
There are 2 protons in a helium atom. Helium is the second lightest element on the periodic table, with an atomic number of 2, indicating the number of protons in its nucleus.
Helium with two protons and two neutrons has a atomic number of what?
Helium with two protons and two neutrons has an atomic number of 2, as the atomic number corresponds to the number of protons in an atom.
Why does helium not have a charge?
all atoms generally do not have charge as the number of protons and number of electrons will be the same.
Which one has fewer protons Nitrogen or Helium?
The periodic table is a good reference - check out the atomic number ! Helium - 2 protons, Nitrogen - 7 protons
Why does helium have an atomic number of 2 and atomic mass of 4?
An atom's atomic weight is the total of all protons and neutrons in its nucleus. Helium almost always contains two protons and two neutrons. Therefore, its atomic weight is 2 + 2 = 4.
What is the symbol for 2 electrons and 2 protons?
Number protons equal to atomic number. So the element is Helium
What is helium's number of electrons?
Helium has 2 protons and 2 electrons.
What is the superscript 4 for helium?
4He or He4. 4 stands for the mass number of Helium Mass number = number of protons + number of neutrons Since the atomic number or number of protons in helium is 2, the number of neutrons in He-4 is also 2.
