The nucleus of a Helium atom contains two protons and two neutrons, protons and neutrons are measured in Daltons, and a Helium atom is about 4 Daltons
The smallest atom is helium (nucleus and electrons) while francium is the largest. Helium: 28 picometer francium: 260 picometer
Helium atom has 2 electrons.
Helium is an element- the second one in the periodic table.

The diameter of a helium atom is approximately 0.1 nanometers, or 1 angstrom. In meters, this translates to about 1 × 10^-10 meters. Helium atoms are among the smallest atoms, with their size largely determined by the electron cloud surrounding the nucleus.
Elements are not species. Helium is an element. Helium can be a single atom.
Helium atom has 2 electrons.
Helium is an element- the second one in the periodic table.
Yes, helium atom.
A neutral atom of helium has 2 electrons.

Helium will not react with carbon as helium is chemically inert.
Helium is a neutral atom that has several isotopes and can become an ion.
The nucleus of a helium atom contains two protons and two neutrons.
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+.
