How are alpha particles written?

Answer 1

An alpha particle can be written as ¸He«+ (Sorry, but it will not print properly on this answer page. The notation should be a superscript 4 over a subscript 2, followed by He, and then a superscript 2 over a subscript 2, followed by a superscript + sign).

Answer 2

The symbol of an alpha particle is 24He2+

The first 2 is the atomic number, the number of protons. The 4 is the Atomic Mass number, the number of protons and neutrons. (It should be written directly over the 2, but that is not possible with the limited graphics we have with WikiAnswers.)The He is the symbol for Helium, because an alpha particle is a helium nucleus. The second 2 and its plus sign indicates the ionic charge is +2, meaning there are no electrons, and that the atom's charge comes from the two protons alone.

Answer 3

Alpha particles are typically denoted as ^4He2 or α, where the superscript 4 represents the atomic mass and the subscript 2 represents the atomic number.
