Why helium is an element?
Helium is an element because it contains only one atom in its simplest form.
After a single subatomic particle is removed from an atom of helium the helium atom becomes an atom of hydrogen What subatomic particle was removed?
Atomic number is reduced by one.So a proton has removed.
How many electrons and prtons are in Helium?
Helium is a non metal element. There are 2 electrons in a single atom.
What is the mass of a single atom of helium?
The atomic mass of Helium is 4.002602. The atomic mass is the combined number of protons and neutrons in the atom.
Is helium atom an aersol?
No. An atom is not an aerosol in any form. An aerosol consists of solid particles or liquid droplets suspended in a gas. Since helium consists of single atoms it is simply a gas.
Nucleus of a helium atom?
there are 2 protons in a helium atom there are 2 protons in a helium atom
How many electrons does heliuim have?
Helium is a non metal element. There are 4 electrons in a single atom.
Is helium element or compound?
Helium itself is an element and it forms no chemical compound whatsoever, therefore, it is a noble gas. The atom of Helium is so inert that it cannot even form a molecule with another atom of Helium, hence is monoatomic.
How many electrons are there in the helium atom?
7 Helium contains two electrons in all naturally occurring states.
How is the nucleus of the hydrogen atom different from the nucleus of the helium atoms?
The hydrogen nucleus has a single proton. The helium nucleus has two protons and one or two neutrons.
What does the mass number in helium represent?
The mass number in Helium represents how much space a single helium atom takes up (not including electrons, because electrons can be bonded, and my come and go)
How many electrons shells does a helium atom have?
The electron configuration of helium is 1s2; two electrons on the first (and the single) electron shell.
