What is atomicity of helium?
Helium is chemically inert as it has completely filled s-orbital. Helium will not form ions or compounds. Hence helium is MONO ATOMIC.
What is helium 's state of matter?
gas
Does helium have the maximum number of valence electrons in its outer shell?
Yes it does. Helium has 2 electrons in the s orbital. A s orbital can hold a maximum of two electrons.
Why is helium atomic number 2?
Helium's atomic number is 2 because it has 2 protons in its nucleus.
Why is helium atom more stable than hydrogen atom?
Hydrogen has 1 proton and 1 electron, helium has 2 protons, 2 neutrons and 2 electrons.
What that atom has 1 neutron(s) and 2 proton(s). What is its atomic number?
This isotope of helium is helium-3; the atomic number of helium is 2.
Heaviest element whose atoms have more s electrons than p electrons?
The heaviest element whose atoms ave more s electrons than p electrons is helium. Helium is found in a wide variety of compounds, including water of H20, for instance.
What charges helium?
helium`s charge is H+, is a positive charge
What is helium's charge?
helium`s charge is H+, is a positive charge
What is atomicity of helium?
Helium is chemically inert as it has completely filled s-orbital. Helium will not form ions or compounds. Hence helium is MONO ATOMIC.
