They are on the outermost level of the electron shells. On the Periodic Table the valience electrons increase as they go over in groups.
Valence electrons are located at the highest energy level present in an atom and they are almost responsible for its chemical properties.
They are the electrons that participate in chemical reactions.

An atom chlorine has several valence electrons in its?
Chlorine has 7 valence electrons in the 3rd electron shell. Chlroine is in the third row of the periodic chart, so its 3rd shell is the valence shell, and it is in the next to last column, 7A, so it has 7 electrons in that 3rd shell.
What are the total numbers of valence electrons in LI2O?
To find the total number of valence electrons in Li2O, we add the valence electrons of lithium (1 valence electron each) to the valence electrons of oxygen (6 valence electrons). So, Li2O has 2 (from Li) + 6 (from O) = 8 valence electrons.
How many valence electrons does Sulfur?
there are 6 electrons in valence shell of sulphur so it accepts two electrons to complete the octet (8 electrons in last shell) so its valency in ionic compounds is always - 2.
What is the total numbers of valence electrons in IBr?
I (if you count the rows) is at the 7th row, so it has 7 valence electrons. The is the same for Br, so there is a total of 14 electrons. :)
Where are valence electrons found?
Valence Electrons are the electrons that are located furthest away from the atom itself in the outermost electron shell. They are located on the last energy level also known as the valence level.
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
Why are electrons so reactive?
Electrons are no reactive by itself but they are important in chemical reactions - valence electrons.
Where are the valance atoms in an atom?
Valence electrons are the outermost electrons in an atom. They are located in the outer energy levels or orbitals, specifically in the highest principal energy level. These valence electrons are involved in chemical bonding and determining the atom's reactivity.

What does the group number of A elements in the AB numbering system tell about valence electrons?
The group number of A elements in the AB numbering system indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on. Valence electrons are important because they determine the chemical properties and reactivity of an element.
How many valence electrons in selenium?
Selenium has 6 valence electrons. It belongs to group 16 of the periodic table, so it has 6 electrons in its outermost energy level.
In a bromine atom which atomic orbitals contain the valence electrons?
* Ground state electron configuration:[Ar].3d10.4s2.4p6 so...4s and 4p
How many valence electrons does AsO2 have?
As,Arsenic belongs to nitrogen family in periodic table so it has 5 valence electrons.
