You can look at the Periodic Table of the elements and determine the number of valence electrons in that element.
The Alkali metals have one
The Alkaline earth metals have two
The Transition metals have one to three, it depends
The Boron family have three
The Carbon family have four
The Nitrogen family have five
The Oxygen family have six
The Halogen family have seven
The Noble gases have eight

How many valence electrons are there in a molecule of crotononitrile?
A molecule of crotononitrile (C4H5N) has 9 valence electrons. This is calculated by adding the valence electrons of each element: carbon (4), hydrogen (5), and nitrogen (1).
How many valence electrons does the compound sulfate have?
The compound sulfate (SO4^2-) has 32 valence electrons. This is calculated by adding the valence electrons of sulfur (6) to the valence electrons of oxygen (6 each for a total of 24), and then adding 2 additional electrons to account for the 2- charge of the sulfate ion.
The outermost electrons in an atom are called?
Valence electrons
What are the electrons in the outmost shell of an atom called?
the electrons in the outermost shell of an atom are considered to be the valence electrons.
Does krypton have 8 valence electrons?
Yes, krypton has eight valence electrons.

What is the number of valence in hydrogen sulfate?
Hydrogen sulfate (HSO4-) has 7 valence electrons. This is calculated by adding the number of valence electrons in sulfur (6 electrons) and hydrogen (1 electron), then subtracting one due to the negative charge on the ion.
