That depends on the reaction, and the gain of electrons is refereed to as reduction.
The Halide gasses (Fluorine, Chlorine, Bromine etc. ) because they only need to gain 1 electron to fill its outermost energy level.
Fluorine is the element that would most likely to gain electrons in a chemical bond
Metals ususally give electrons, and nonmentals usually gain electrons.
fluorine chlorine sulfur oxygen nitrogen
Fluorine
Oxygen is the eighth element in the periodic table.8 protons and 8 electrons. The no of protons will always be the same as the no of electrons unless in witch case it would be referred to as being ionised or a free radical.
Any atom of any element has no net electrical charge. The number of "outer" electrons is irrelevant, because the charge of all the electrons is balanced by an equal number of protons in the nucleus of the atom. However, the number of outer electrons is highly relevant to the charge of the most likely ion formed from an atom of an element by chemical reaction: Magnesium and other atoms with two outer electrons almost always form cations with 2 net positive charges when the atoms react chemically with some atom of another element, because these two outer electrons are less tightly bound to the atomic nucleus than any other electrons of the atom.
It would belong to group XVI, the group with oxygen.
The charge an element would have if it lost or gained electrons
Because they both have a different number of valence electrons in their outer shells, and that is what determines the properties of the element.
Li, or lithium, is the element most likely to lose electrons in a chemical bond. Lithium has 1 valence electron.
The charge an element would have if it lost or gained electrons
Metals are the elements that usually lose electrons in their chemical reactions. This is because they have few electrons in their outermost shells which are easily lost.
Chemical Reactions would not exist, since unstable electrons are needed to start a Chemical Reaction, All the molecules would be stable, so they would not need to undergo change to become more stable.
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.
The more electronegative element. Nonmetals have enough electronegativity advantage over metals to do this.
They determine many things. They can be used to predice hybridization, determine octet, be used to assign formal charges. The simplest answer would be for a intro to chem class, they determine the number of electrons in the atom's "outer ring"
There is no element with a "charge of 18". Charges are determined by electrons, so for an atom to have a charge of ±18, it would have to lose or gain 18 electrons - something an atom wouldn't do. Perhaps you mean atomic number of 18, which would be argon or Ar.
Oxygen is the eighth element in the periodic table.8 protons and 8 electrons. The no of protons will always be the same as the no of electrons unless in witch case it would be referred to as being ionised or a free radical.

An element you have a +2 charge It is had lost electrons. It would have to lose the same number of electrons that its positive charge is. So it would have lost 2 electrons.
