All halogens (fluorine, chlorine, bromine, iodine and astatine) have 7 valence electrons.
Halogens have seven valence electrons. Other elements dont have seven valence electrons.
All halogens (fluorine, chlorine, bromine, iodine, astatine)

Transition elements can form bonds by losing electrons from both the outermost and next to the outermost principal energy levels.
Covalent Bonds. :)

Reaction between atoms involve only valenceelectrons (electrons in the outermost shells of atoms).
Atoms don't do anything. If the electrons go to a higher energy state, they use energy. If they fall back to a lower state, they release energy. This shouldn't affect the entire atom, just the electrons.

Atoms can fill their outermost energy level by either gaining electrons from other atoms or by sharing the outermost electrons with another atom.
Yes, the outermost energy level of the atoms of the noble gases are filled, meaning that they have the maximum number of electrons. This is why noble gases are stable and unreactive. The atoms of reactive elements share or transfer electrons in order to fill their outermost energy levels, making them stable like the noble gases.
Tungsten atoms contain six energy levels (shells). The outermost energy level is the sixth energy level. It has two electrons in the 6s sublevel.

Electrons; valence electrons are on the outermost level
no, electrons can

The sharing of electrons in the outer energy levels of two atoms is called bonding.
