sorry some stupid kid put it in i dont have an answer sorry
well neutron in 10 protons

Lead, magnesium, aluminum, and silicon are different elements, each containing an unique number of protons in the nucleus as well as different numbers of valence shell electrons that influence how they react with other elements and form bonds. Elements are also classified into types depending on their properties and position in the periodic table. Magnesium is an alkaline earth metal, which are soft and silver coloured. Lead, on the other hand, is a heavy metal. Aluminum is classified more ambiguously under 'other metals', and silicon is a metalloid.
Sodium has one valence electron, magnesium has two. If this valence electron is lost, then noble gas configuration is obtained. It is easy to lose one electron than two, so sodium is more reactive than magnesium
Magnesium has 12 protons and 12 or so neutrons depending on the isotope. An alpha particle has 2 protons and 2 neutrons. So if magnesium loses 2 protons by shooting off an alpha particle, it will move 2 places down the periodic table and become neon. Neon has 10 protons.
well neutron in 10 protons
Magnesium
magnesium-25 is "heavier", it has one more neutron in the nucleus
12 protons and no electrons

the best answer is 12
Ribosomes are produced by the nucleus.
All the elements have a nucleus. The nucleus contains protons and neutrons. Electrons move around the nucleus.
Beta is produced by the weak nuclear force.n --> p + e- + v, decay to electron & antineutrinop --> n + e+ + v, decay to positron & neutrinoThe leptons do not preexist in the nucleus, their wavelength would be too long for that.I think you are confused when you say "contain no elements". No nucleus contains elements, the nucleus is part of an atom and atoms are part of elements & compounds.Perhaps you meant to say "contain no electrons". If so you are right, see above. The leptons (electron, positron, neutrinos) are created by a decay process mediated by the weak nuclear force.
All the chemical elements have an atomic nucleus.
An isotope can be produced if a nucleus gains a neutron or if one of the protons in its nucleus decays into a neutron and positron.
Summer school sucks i know. The answer is They were produced by nuclear reactions.
