that would depend on what specifically the were reacting with on each instance.
they lose them. oxygen is nice :p
No, they gain only one electron per atom.
The atomic number tells us the number of electrons and the number of protons., i.e. Atomic Number = Number of electrons = Number of Protons. The atomic mass tells the total number of particles in the nucleus, i.e. Atomic Mass = # of protons + number of neutrons. The Group number is the heading at the top of a column in the table. It tells the the outer electron configuration of the atom. This determines many chemical properties of the element.
You question is not very clearly stated but I think I know what you are asking. As you go down the column of any family of elements in the periodic table, you move to increasingly heavier and larger atoms. Their outer electrons are therefore farther from the nucleus, and even though the nucleus is larger and has a larger positive charge, the increased distance is the predominant influence, making the outermost electrons less tightly bound, and therefore more easily ionized, with a lower ionization energy.
The silicon based product of the earths crust in the oxygen, nitrogen, and halogen family. include many oxygen including selenium and tellurium frog through its skin.
Electronegativity and first ionization energy both increase going up the Periodic Table.
THis is because they have the same properties, therefore, they react the same way.
Because all the atoms of these elements in Family 18 have filled outermost energy levels.
Elements in group 1 have a lower number of electrons with respect to the other elements in the same period.
similar chemical properties and characteristics
those elements are in the same 'family' or 'group'
Elements in the same family, or group will contain the same number of valence electrons and have many similar characteristics.
Because their outer electronic structure is nearly the same, they also have the same amount of valence electrons, so it leads to similar chemical reactions (or similar bonds with other atoms)
A family is a column in a periodic table; all elements in a family have similar physical and chemical properties, because they have the same numbers of valence electrons (outer electrons).
Elements in the same family (or group) have the same amount of electrons in their outer shell. For Example, all elements in Group 1 have 1 electron in their outer shells.
This is the alkali metals family; the ionization energy is lower for these chemical elements.
All elements have same number of valence electrons (two) and hence they have similar reactivity and chemical properties.
Alkali metals lose one electron in chemical reactions.
