Nothing. Group II metals are reactive, but the group 18 or inert gases are not.
Is the direct displacement of atom or group of atom by atom or group of atom.
An amino group and an R group
Protons and Neutrons are in the Core of an atom, and Electrons orbit around this Core.
Group one metals are the Alkali Metals, but Hydrogen is placed in group one because of its electron arrangement. All group one metals have one electron in their valence shell (outer most shell) and hydrogen is no exception. It has one electron in its last shell, and is therefore placed in group one even though it is not an alkali metal.
The four groups that surround the central carbon atom in an amino acid are COOH group, NH2 group, H atom and R group which could either a Hydrogen atom or an alkyl group.
An amino group and an R group
The atom becomes a negative ion.
a nitrogen atom in an amino group and a carbon atom in a carboxyl group
Chemical elements in the periodic table are placed in 18 groups (columns); the number of electrons in this level is 1 to 8.
there will be no formation of world
A charged atom or group of atoms are known as ions or radicals.
A hydroxyl group is an -OH group, consisting of a hydrogen atom bonded to an oxygen atom, which is covalently bonded t the rest of a given molecule.
