Only chemical elements have a valence.
2
The valence of chlorine is -1.
NaCl has an ionic bond, chlorine has one valence electron, sodium also.
electrons in Na2O
Before : One electron in the valence shell After reaction w/ Cl gas: none electron in the valence shell
no it does not. NaCl is a neutral compound.
The NCl3 molecule, like most other stable molecules, exist because they share electrons in such a way as to close out the valence shell. Therefore, although one usually doesn't say so in regards to molecules, NCl3 has 8 valence electrons.
NH3
RbCl because Rb has more valence electrons
Valence number is the number of chemical bonds that an element can form- these bonds may be covalent (sharing of electrons) or ionic (transfer of electrons). A valence number of 1 means that the element forms just one bond, for example sodium -- forms NaCl - with an ionic bond; hydrogen forms HCl - with a covalent bond.
Na+ and Cl- ions are formed, which then results in the formation of the ionic compound NaCl.
1 mole NaCl = 58.443g NaCl 234g NaCl x 1mol NaCl/58.443g NaCl = 4.00 moles NaCl
1 mole NaCl = 58.44g NaCl0.48mol NaCl x 58.44g NaCl/1mol NaCl = 28g NaCl
