Boron, Krypton,Neon, and Radon Krypton, Neon and Radon do not gain electrons. Because an atom wants to have eight electrons in their valence shell or their outermost shell, and Krypto, Neon and Radon are Noble Gases which already have eight in their valence shells, so they don't lose or gain electrons. And as for Boron it want's to gain 5 electrons because it only has three in its valence shell.

Do atoms of the halogen family of elements typically gain two electrons when they react?
No, they gain only one electron per atom.
The elements in group 7A have one valence electron true or false?
A valence electron, or valence electrons, are found in all of the elements. A valence electron is an electron located on the out most shell of an element (the valence shell). Most elements will have more than one valence electron. Oxygen, or O, has six valence electrons because its outer shell consists of six electrons.
How many valence electrons does gold have?
The number of electrons in a neutral atom of any element is the same as the number of protons in the nucleus of the atom. The number of protons in an element is the same as the atomic number for that element. In the case of Gold (Au) the atomic number is 79.
How many protons and neutrons are in chlorine and sodium'?
The number of protons and neutrons is not changed; sodium lose one electron and chlorine gain an electron.
What would you get if you took an electron away from an atom?
You would get a positive ion, because there will be one extra positive charge no longer offset by the negative charge of that electron. You cannot take away a proton without changing the element, but you can add or remove valence electrons.
How many electrons does iodine lose or gains when it forms a ion?
Iodine tends to gain one electron when it forms an ion.
Which group of elements on the periodic table tends to form ions?
Group one, not including element 1 (helium) tend to form ions.
What atom tends to gain one electron when it combines with another atom?
All elements in the 7th family/group (2nd from the right) on the Periodic Table.
What kind of atom tends to have one electron?
The hydrogen atom has 1 electron.
How many electrons will fluorine gain or lose when forming an ion?
There is only one possibility for the ion form of the element fluorine:fluoride, F - , oxidation state -1.It is the most electronegatve element of all, so there is no other element able to abstract one ore more electrons FROM Fluorine.Fluoride is formed by the following reaction:F2 + 2e- --> 2 F-
Which is more reactive fluorine or barium and why?
Fluorine would be the more reactive element because it needs to gain one electron. While Barium needs to gain two electrons. Thus it is easier to gain one than to lose two.
What groups of elements on the periodic table tends to form ions?
Alkali metals group tends to form ions.They give single electron to gain positive charge.For example : Sodium give one electron to become Na+ ion.
Does astatine lose or gain electrons?
Gain of one electron
What kind of a tomb tends to lose one electron?
An atom with single electron in its outermost shell
What two entities are formed when one element transfers an electron to a different element which can accept the electron?
A positive ion ( the one that gives the electron) and a negative ion ( the one that accepts).
How many electrons will sodium gain or lose in forming an ion?
Because Sodium is in group 1, it tends to lose one electron when forming an ion, therefore having a charge of +1
What is an example of How ions form?
Ions are formed when elements either gain or lose their electrons. For example, Sodium (Na), since it has one electron in its outer shell (valence electron) it will be easier for the atom to lose its one valence electron and give it to an element that would want to gain that one electron, for example, Chlorine. This reaction of gaining or losing electrons would create an either negative ion (gained electrons) or a positive ion (lost electrons). For the example that I did, the element Sodium would lose its one electron in its outer shell making it Na +1 because it would have one more positive charge then it would negative charge.
