Where are the valence electrons in an atom?
In the outermost shell that has electrons in it, those are called the valence electrons. For example carbon has 6 electrons, but only 4 are valence electrons because there are 2 in the shell in between it and the center of the element and 4 on the outside shell.
If an atom has 7 electrons how many electrons are located in the second energy level?
An atom with seven electrons will have five electrons in the second energy level.
Where are valence electrons located and why are they so important?
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.
Location of electrons?
Electrons are naturally to be found in shells surrounding atomic nuclei.
When atoms combine with other atoms interaction occurs between their?
Interactions occur between their eletrospheres, where their valence electrons are located.
How electrons work?
Electrons have negative charges, and unlike neutrons and protons are located on the outside of the atom. They are generally located in electron clouds around the atom, and stay there because of their attraction to protons that are in the nucleus of the atom.
Elements, like calcium, located toward the top of a group have a high attraction for their valence electrons because they have a _?
small atomic radius.
Are valance electrons located near the nucleus?
Valance electrons are not located near the nucleus. These electrons are in fact located the furthest away from the nucleus compared to other electrons.

How many electrons are in mercury and where are they located?
There are 69 electrons.
Would the trend in atomic size cause an increase or a decrease in the attraction between the nucleus and the valence electron within the group as the atomic number increases?
Atomic size increases from top to bottom in a group due to increase in theshieldingeffect.As you go down the group shielding from core electrons increases (as more core electrons are added), therefore valence electrons experience weaker attraction forces from the nucleus and are located further away from it, resulting in an increase in size.If you move across a period the attraction between the nucleus and valence electrons increases because the number of protons and the number of valence electrons both go up whereas the number of core electrons stays the same (shielding decreases). In this case the size decreases.
In an atom electrons are what?
valence electrons are the electrons located in the outer shell of an atom which are available for reaction
Where are the valence electrons in an atom?

How does the number of valence electrons that carbon has affect the number of bonds that carbond can form?
if the number of electrons are greater in energy levels or shell so greater will be the nuclear attraction because of greater nuclear attraction the atom will be greatly able to attract other atoms towards their self and easily form bond between them..
What are the Electrons on the outer level of an atom called?
The electrons located in the outer shell are called "valence electrons".
What are valence electrons in an atom?

What particles are located in the electron cloud?
Electrons are the particles found in electron clouds.
