The valence shell is the outermost electron shell containing electrons.
Potassium has one electron in its outer shell, assuming it's not an ion.
Krypton is a noble gas; it has 8 electrons in its valence shell.

The expected number of valence electrons for a group 3 A element is 5 number of valence electrons.
2 is the standard number of valence electrons
Helium has 2 valence electrons.
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
Valence electrons and group number for metal are same. For non-metals, valence electrons are equal to group number-10.
Both lithium and potassium have one valence electron
The elements that have the same number of valence electrons are located in a group.The group number from the Periodic Table relates to the number of electrons in the valence shell.For example, elements in group 1 (H, Na, Li, K, Rb, Cs, Fr) all have 1 valence electrons and elements in group 7 (Cl, F, I, Br) have 7 valence electrons in its outer shell.
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
Two valence electrons.
3 electrons !
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
the number of valence electrons is the number group on the table its on
The group numbers tell the number of valence electrons. Without looking on the group number you can also tell the number of valence electrons by looking at the highest energy level in the electronic configuration.
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
The expected number of valence electrons for a group 3 A element is 5 number of valence electrons.
Valence electrons describe the number of available electrons for bonding. The group number describes outermost electron. The elements in same group has same valence electrons.The number of electrons available for bonding are the valence electrons. In an element, the group number is equal to the number of valence electrons. So the number of electrons available for bonding can be identified by the group number.
2 is the standard number of valence electrons
