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 ... WebOct 31, 2024 · Since the total charge of the atom had to be neutral, then the electrons must be very very tiny and swimming, orbiting or dancing around that nucleus in a loose cloud. …

WebWatch on. Dogs, in their current form and as we know them today, are believed to have evolved from wolves. Through a process of domestication that began as far back as an estimated 15,000 years ago, dogs slowly became separate from their wild wolf ancestors. So, it’s highly likely that dogs as a species would have existed even without humans. WebApr 20, 2024 · The ground state of an electron, the energy level it normally occupies, is the state of lowest energy for that electron. There is also a maximum energy that each electron can have and still be part of its atom. Beyond that energy, the electron is no longer bound to the nucleus of the atom and it is considered to be ionized. shoe moulding
