The hybridization will be sp3. I hope that is helpful.
-1
An ion is an atom which has gained or lost electrons.
Atoms want to have full outer shells of electrons.
Electrons are negative.
Fluorine has 7 electrons in its outer shell. When it gains one to fill its shell it will be made negative.
Thus the charge of a fluorine ion is -1
Halogens are among the most reactive of all elements. They have seven valence electrons, so they are very “eager” to gain one electron to have a full outer energy level. So they gain
A number that shows the size or amount of something. Usually the number is in reference to some standard measurement, such as a meter or kilogram. Here some scales are used to measure weight.
