Deuterium, an isotope of hydrogen, has an Atomic Mass of 2 since it has a neutron as well as a proton in the nucleas. Hydrogen oxide, H20 is known as water - deuterium oxide is known as heavy water.
Well that is a Helium atom. However, the answer probably being looked for is an alpha particle (which is a helium nucleus)
Helium has the atomic number two. This means it has two protons in its nucleus.
None of them.
Helium
Beryilium
The atomic number of Helium is 2.
The atomic number of helium (He) is 2.
The atomic number of the element refers to the number of protons of an atom: all atoms of an element have this number of protons. A neutral atom of the element will have the same number of electrons.
It can make maximum 2 covalent bonds as element of atomic number 7 has 5 valence electrons while element having 16 atomic number have 6 valence electrons.
Hydrogen is a non metal element. Atomic number of it is 47.
Aluminium is a metal element. atomic number of it is 2.
The atomic number of Helium is 2.
The atomic number of an Element refers to it's position in The Periodic Table. The first element (Hydrogen - H) has the atomic number 1. The second element (Helium - He) has the atomic number 2. The fifty-second element (Tellurium - Te) has the atomic number 52. And so on.
The atomic number of helium (He) is 2.
Helium is a gas element. atomic number of it is 2.
Atomic number 2 is Helium, which has the symbol He
The average number of neutrons that a specific element has is equivilent to the element's atomic mass minus the that elements atomic number. For example Helium has 2 neutrons because its atomic mass (4) minus the atomic number (2) is 2.
2 He 4.00260 has several components. The first number, 2, is the atomic number of the element. This equates to the number of protons in the element. The second component is He, which is the atomic symbol of the element. Finally, 4.00260 is the atomic mass of the element. In this case, the element described is helium.
We can find helium as a non metal element. Atomic number of it is 2.
Helium is a gas element. atomic number of it is 2.
Calcium has the atomic number 20.
