How many electrons does a neutral atom of helium (He) have?
A neutral atom of helium has 2 electrons.
How many times heavier is a sulfur atom than a helium atom?
A sulfur atom is about 32 times heavier than a helium atom. This is based on the atomic masses of sulfur (32 amu) and helium (4 amu).
What atom contains 1 electron and 2 protons?
None, for it to be an atom it has the have the same number of electrons and protons. Something with 1 electron and 2 protons would theoretically be a helium ion but helium does not form ions.
Is HE an element or a molecule?
If HE was a compound it would be a compound of H (hydrogen) and E (sorry there is no such element).If HE is an element then it is misspelled and should be He (helium).
Ionization energy of a helium atom is helium gas per mole?
the first inoization energy is 2372.3 kJ mol-1 there are 6.0221415 × 10^23 in a mole from avagadros number, devide the ionization energy for one mole by the number of atoms in a mole and you get the first ionization energy for one atom.
Is helium atom a single atom species?
Elements are not species. Helium is an element. Helium can be a single atom.
How many electrons does an atom of helium have atomic?
Helium atom has 2 electrons.
Is 1 helium atom an atom?
Helium is an element- the second one in the periodic table.
Is 'He' an atom?
Yes, helium atom.
How many electrons does a neutral atom of helium (He) have?
A neutral atom of helium has 2 electrons.
Draw atom with mass number 4 and atomic number 2?
Helium is a non metal element. Atomic mass number of it is 4.
Is the difference between helium in a jar in helium?
helium in a jar diff from helium atom
What type of bond would be formed between a carbon atom and a helium atom?
Helium will not react with carbon as helium is chemically inert.
What is a Nucleus of a helium atom?
The nucleus of a helium atom contains two protons and two neutrons.
Is helium an isotope atom or ion?
Helium is a neutral atom that has several isotopes and can become an ion.
When a helium atom loses an electron then what is formed?
When a helium atom loses an electron, it forms a helium ion which is positively charged because it has one less electron than protons. This helium ion is written as He+.
How many kinds of atoms does helium have?
Helium has one kind of atom: helium.
