Atone
Gallium is a mono-atomic metal element. So their atoms are atoms, and as many as you have!
the valence electrons cause the chemical reations. the valence electrons decide that element attract to which element.
the number of valence electrons in the atom's outer shell how much the valence electrons are shielded from the nucleus
elements, or atoms, do not have valence numbers, they have valence orbitals (the outermost one) or valence electrons (all the electrons in the outermost orbital). you can look this up anywhere that shows the electron configuration, like your periodic table.
For doing so, firstly the electronic configuration of the element is written.Then it is seen how many electrons does the element has in its valence shell.The max. no. of electrons that can be present in the valence shell is 8. So, if the element has less than 4 electrons in the valence shell, then it looses them to form stable ion and if it has more than 4 electrons, it must gain 8-no. of valence electrons to form stable ion. If the element has 4 valence electrons, then it shares them with other atoms to form compounds.

borin has more valence electrons than kernel electrons
A reaction in which the atoms in an element lose electrons and the valence of the element is correspondingly increased.
Gallium is a mono-atomic metal element. So their atoms are atoms, and as many as you have!
the valence electrons cause the chemical reations. the valence electrons decide that element attract to which element.
the element with seven valence electrons will be more reactive. The reason for this is that elements want to always want to have a full valence shell (they always want 8, like a noble gas). The element with eight valence electron is happy with its full shell and will not want to get rid of any electrons.

It depends on the number of electrons in the outer valence shell in the atom
its Atomic Mass.
For most atoms, it is 8 valence electrons, usually referred to as an octet.
