Want this question answered?
The element with 1 electron in period 1 would be hydrogen.
Hydrogen has 1 valence electron, whereas helium has 2 valence electrons.
Silicon is p-block element. It has 4 valence electrons. It is present in group-14.Titanium has 4 valence electrons. It is in the third period. Titanium is a metal element.
an element with 2 valence electrons can obtain a stable electron configuration by "kicking out" two electrons to have the same electron config as the noble gas in the previous period
Helium is an element. It is a noble gas. It is in the 18th period.

The element would be potassium (K).

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.
Helium. It has 2 electrons in its single shell.
Selenium. As you go across the groups, not counting the transition metals, a valence electron is added.

Electron configuration is the arrangement of elements according to their increasing atomic numbers whiles period is the arrangement of elements according to the increasing number of valence electrons.
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.
First of, Valence electron ground state is the number at the end of a Electron configuration in period 2 which goes across (from left to right) you see that each element has 2 numbers on the electron configuration ex Li 2-1 Be 2-2 B 2-3 C 2-4 notice that the ground state (which is the last number is in the secoond shell (I THINK)
