WebJun 11, 2009 · PS We do know that whenever anti-matter annihilates with matter, it produces an equal amount of matter and antimatter, so this in itself does not prove that antimatter has positive mass. But matter - anti-matter annihilation at rest produces 2 x the rest mass energy of one particle (e.g., electron or proton) so we can say that matter and anti ...
WebWe know that atoms with different numbers of protons in their nuclei are different elements. The same is not true when it comes to neutrons, though: atoms of the same element can contain different numbers of neutrons in their nuclei and still retain their identity. WebYou are given an element or iron name and an atomic number. We ask you till tell us about what it composed of. An atom is composed of protons, neutrons, and electronic. The proton and neutrons been finding in that nucleus. The electrons are found in the electron cloud, which is an area that surrounds the nucleus.
