I think it is seaborgium. Symbol Sg. Atomic # 106.
The element with 99 protons is Einsteinium, with the chemical symbol Es. It is a synthetic element named after physicist Albert Einstein. Einsteinium is not found naturally and is produced in nuclear reactors or particle accelerators.
Yes and no; the number of protons determine the valance number of electrons. The valence level of electrons and how full/empty it is largely determines an elements chemical behavior. I would say that valence electrons are the main determinant, but that is predetermined by protons.
It would by definition be Helium (atom number = number of protons = 2) but the nucleus of the stable isotope 4He also contains 2 neutrons (the mass number = total number of p's and n's = 4)
An atom contains protons,neutrons and electrons. An atom is very small.In order to see it you have to use a special microscope. Edit: The atom is made up of three main particles: neutrons, protons, and electrons. The atom is completely unique, but is hard to pinpoint, because we're discovering more and more about it all the time. It's full name is "Atomos", meaning: "Can not be broken down". In simpler words, it means it's tiny and EVERYTHING is made out of it.
Beryllium for example would be. 7 2 Be 4 7= The mass number (+Protons and +/- neutrons added) 4 = The +protons 2 = The oxidation state. Beryllium would have 2 valance -electrons, hence the two. It has to lose 2 -electrons to be stable. For a metal it would be how many electrons it has to gain to be stable (Full valence shell). Be = Is obviously the symbol of the element.
The transition metal is Manganese (Mn). It has atomic number 25, which means it has 25 protons, ten short of a full deck which would be Iron with 26 protons. It is commonly used in steel production to increase strength and hardness while maintaining flexibility.

Ideally, all elements should have the same number of protons, neutrons and electrons unless they become ionic. This is how elements such as the noble gases remain stable. They the same number of electrons, protons, and neutrons, and a full octet.

An element must have full valence shell in its neutral state, thus having 2, 10, 18, 36, 54, 86, or 118 protons. This places it into the 8A group which are the halogens.
Each element has a specific number of protons in the nuclei of its atoms. This number is known as the atomic number for the element. For instance, the atomic number of hydrogen is one because it has a just one proton in its nucleus. The atomic number of oxygen is eight, again because it has eight protons in its nucleus. For a full summary see the link for the periodic table.
'S' look for it on the periodic table for full name.
It means that the person is not very smart. It is a reference to playing cards. A "full deck" of standard playing cards is 52 cards. If you have less than 52 cards you don't have a "full deck" and it will be difficult (and not smart) to try to play card games.Not playing with a full deck means a person is not very smart.
Well there are 52 cards in a full deck. There are four 3's in a full deck, so the probilitiy of selecting of 3 out of a deck would be 4/52.. so the odds are 1 out of 13 OR 7.69%
The element in question is magnesium. It has 12 protons (more than sodium and less than argon), 2 more valence electrons than oxygen (which has 6), and 8 fewer valence electrons than neon (which has a full valence shell with 8 electrons).
Yes and no; the number of protons determine the valance number of electrons. The valence level of electrons and how full/empty it is largely determines an elements chemical behavior. I would say that valence electrons are the main determinant, but that is predetermined by protons.
