How can you determine how many valence electrons an element has?

Simple way - Use the last digit of the group number. (/!\ WARNING! This only works for s-block and p-block elements!) e.g:
Li = 1
C = 4
O = 6
Ne = 8
Correct way - Use the electron configuration (sum of outermost s and p orbitals). e.g:
Fe = [Ar] 3d6 4s2 = 2
Pb = [Xe] 4f14 5d10 6s2 6p2 = 4
U = [Rn] 5f3 6d1 7s2 = 2

How many valence electrons should an element to react with a element with 7 valence electrons?
one valence electron
What are valence electrons and what do they determine?
They determine many things. They can be used to predice hybridization, determine octet, be used to assign formal charges. The simplest answer would be for a intro to chem class, they determine the number of electrons in the atom's "outer ring"
How many valence electrons does an element in 5A contain?
5 valence electrons.
Element 3 lithium has one valence electron and element 4 beryllium has two valence electrons Element 5 boron has how many valence electrons?
Boron has 3 valence electrons.Boron has 3 valence electrons.
How can you determine the number of valence electrons in an atom?
You can determine how many valence electrons an atom has by what family the element of the atom is in. For instance, if the element is in family 8A, the number of valence electrons will be 8. Or, if the element is in family 2A, the number of valence electrons for the atom will be 2. So, whatever number family the atom is in, the number of valence electrons equals that.

Why do scientists group elements with similar amounts of neutrons?
They don'tThey group elements with the same number of valence electrons.The valence electrons of an element determine how that element bond and how many bonds it forms.So elements with the same number of valence electrons tend to have similar chemical properties.
How many valence electron does chlorine?
