HOW MANY VALANCE ELECTRONS IN NF3?
There are 7 valence electrons in an NF3 molecule. Nitrogen has 5 valence electrons and each fluorine atom contributes 1 valence electron, totaling 3 electrons for the 3 fluorine atoms.
How many valance electrons does oxygen have?
Oxygen has 6 valence electrons. A person can determine the number of valence electrons by looking at the periodic table. since oxygen is in the 6th column form the left, it has 6 valence electrons.
How many valence electrons does an atom of any halogen have?
A halogen is located in group 17 of the periodic table, so the electron configuration for the valance electron would be ns2np5 (n=energy level). So all halogens have 7 valance electrons.
What is the difference between a positively and negatively charged atom and how does it occur?
The difference is how many protons and electrons. Protons are positive, (both "p's" easier to remember) so if there are more electrons it's negative, less electrons it's positive. When atoms have electrons added or subtracted it changes the charge, then they are known as ions. The atomic number is how many protons there are, this never changes, if it does there is a different element.
How many electrons are needed for OF2?
For OF2, oxygen (O) has 6 electrons, and fluorine (F) has 9 electrons each. Therefore, the total number of electrons needed to form OF2 is 6 (from oxygen) + 2 x 9 (from two fluorine atoms) = 24 electrons.
How many valance electrons are in trivalent atoms?
14
How many valance electrons to Atoms of oxygen and sulfur have?
Oxygen atoms have 6 valence electrons, while sulfur atoms have 6 valence electrons as well.

What are atoms that receive electrons and become negatively charged?
Basically the nonmetals. Many of them receive electrons, like oxygen, nitrogen, selenium, tellurium, and many others.
