Two electrons imply that the element is in the second period. The 4 valence electrons says that it is located in group 4A (or group 14 in modern notation). Hence, this element is carbon.
The element has 2 electron shells means the element is in the 2nd group. This element is carbon. It has 4 valence electrons.

How many electron shells and how many valence electrons are in an atom of an element found in period 3 and group 16 of the periodic table?
This element is sulfur; the electron configuration of sulfur is [Ne]3s23p4. Sulfur has three electron shells cotaining 2, 8 and 6 electrons. The last six are valence electrons.
What element has 3 electron shells and 4 valence electrons?
Silicon. Electronic configuration [Ne]3s23p2

How many valence shells does the element neon have?
Period number = no. of electron shells. Therefore neon has two shells.

Electron shells
How many valence electron does Sr have?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Are electron shells and valence electrons the same thing?
Valency is the number of electrons in the outer shell the charge is how many electrons is needed to form an octet (full valence = 8 electrons) Eg. Sulfur valence = 6 charge = -2 (needs to gain 2 electrons to gain an octet)
What determines the properties of an element?
The three factors determine the chemical properties of an element:The number and arrangement of electrons in an atomThe number of valence electronsThe number and arrangement of electrons
Group 1a elements have how many electrons in their valence shells?
All these have one electron in their valence shell.
What is the number of valence electrons in selenium?
Selenium has 6 electrons in its outermost shell.
What patterns are noted in the electron structures of elements found in a periodic and in a family in the periodic table?
The period (row) indicates how many electron shells the element has and the family (column) indicates how many valence electrons the element has.
