What are valence electrons and why are they important?
The electrons that occupy the outermost shell of an atom are called valence electrons. Valence electrons are important because they determine how an atom will react. By writing an electron configuration, you'll be able to see how many electrons occupy the highest energy level.

How do you calculate valence?
The ones digit in the group number is the number of valence electrons. To solve without a periodic table, find the electron configuration of the element and count the electrons into 1 group of 2, and then into shells of 8. The number in the last group is the amount of valence electrons.
How do you find the valence of an element?
For neutral atoms, the number of valence electrons is equal to the atom's main group number. The main group number for an element can be found from its column on the periodic table. For example, carbon is in group 4 and has 4 valence electrons. Oxygen is in group 6 and has 6 valence electrons.

What is the charge of a titanium ion with 18 electrons?
So, if an atom of titanium has a different number fo electrons, then said atom is actually an ion, meaning that it carries a net charge. For example, titanium can lose four electrons to form the titanium(IV) cation, Ti4+ . This ion has 22 protons and 18 electrons.
How do you find the valency and atomic number?
Mathematically we can say that if the outermost shell of an atom contains 4 or less than 4 electrons, then the valency of an element is equal to the number of electrons present in the outermost shell and if it is greater than 4, then the valency of an element is determined by subtracting the total number of electrons …
What is the easiest way to find valency?
The valency of an atom is equal to the number of electrons in the outer shell if that number is four or less. Otherwise, the valency is equal to eight minus the number of electrons in the outer shell. Once you know the number of valence electrons, you can easily calculate the valency.
