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"

They also determine the group that the particular element belongs to in the periodic table
Wiki User

Does selenium and bromine have the same number of valence electrons?
No, Selenium has 6 valence electrons while Bromine has 7. You can determine this because on the periodic table, Selenium is in Group VI while Bromine is in group VII.
How many valence electrons does Bi have?
5 valence electrons.
How many Valence electrons now surround oxygen?
6 Valence Electrons
How many valance electrons does helium have?
Helium has two valence electrons. It is the only noble gas not to have eight valence electrons. Helium has the electronic configuration 1s2.The Noble gases have eight valence electrons in their outer shell.
How many valence electronss does each fluorine atom have?
Fluorine is a halogen. All halogens have 7 valence electrons. There are thus 7 valence electrons for Fluorine, 2 in the 2s orbital, and 5 in the 2p orbitals.
What type of properties do valence elcectrons determine for an element?
Valence electrons determine the reactivity of the element.
What are the electrons in the outermost shell that determine bonding?
Valence Electrons
How can you determine the number of valence electrons an atom has?
The valence is determined experimentally.
What do these valence electrons do that make them are so important in chemistry?
the number of valence electrons determine the reactivity of the atoms
What are valence electrons and what do they do?
They determine how great is the valence of a chemical element; they are the electrons involved in the formation of a chemical bond.
The valence electrons are?
Valence electrons are: In chemistry, those electrons found in orbits farthest from the nucleus of the atom. These electrons determine the way in which the atom will combine with other atoms, and thus determine its chemical properties.
Why is so much emphasis placed on valence electrons?
The valence electrons of an element are mainly what determine an element's properties.
What determines an elements property?
Chemical properties of an element determine by the number of electron
What do Valence Electrons determine?
The Group Number of the Element you're working on determines the number of Valence Electrons. Valence electrons are electrons in the outside energy level.
Which subatomic determines the atoms chemical properties and why?
Valence shell electrons or valence electrons determine the chemical properties of an atom...
What re valence electrons?
Valence electrons are: In chemistry, those electrons found in orbits farthest from the nucleus of the atom. These electrons determine the way in which the atom will combine with other atoms, and thus determine its chemical properties.
What terms is used to the electrons in outermost shell or energy level?
Valence electrons are the electrons in the outermost shell. They are the electrons available for bonding and generally determine the number of bonds an atom can make
