Yes, here is a dative bond.
Yes it will form ionic bond (as in NaF or MgF2) or covalent bond as in F2 or ClF3)
Fluorine gains an electron. Fluorine is very reactive and will form bonds.
ClF3 exists but FCl3 does not because the Cl has vacant 3d orbits orbitals and can thus combine with three F atoms but F does not have any d-orbitals and thus it cannot show the oxidation state of +3 and bond to 3 Cl atoms.
Its molecular
5.88 mg ClF3 (1 gram/1000 mg)(1 mole ClF3/92.45 g)(3 mole F/1 mole ClF3)(6.022 X 10^23/1 mole F) = 1.15 X 10^20 atoms of fluorine
trigonal bipyramidal
Yes, completely.
molecular
Electrons are shared in a type of bond known as covalent. This type of bond is also considered a chemical bond.
The formula for chlorine trifluoride is ClF3
Yes. It is polar. It is not an insoluble salt.
