Period six on the Periodic Table starts the row after Xenon. The electron shell 6s2 6p2 corresponds to the atomic number 82. This is lead.
group 8A and period 3, so its argon
The electron configuration of argon is [Ne]3s2.3p6.
1. the noble gas krypton (Kr).

A molecule of methane contains 8 valence electrons: 4 from the carbon atom and 1 from each of the 4 hydrogen atoms.
A neutral atom of silicon will have 4 valence electrons. The amount of valence electrons that a neutral atom will have can be found by the atoms group number in the periodic table.

The element with atomic number 28 is Nickel (Ni). It is a transition metal in period 4 of the Periodic Table. It is the first element in the Nickel family. It has 28 electrons in 4 shells with 2 electrons in the outer shell.
Carbon has 4 valence electrons. It needs four more to form the octet. So carbon will share four 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.
Al
chromium (Cr)
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.
Only nitrogen (but in the period 2) has 7 electrons in the neutral atom.
Germanium in the 4th period has 4 valence electrons.It has electronic configuration of 2 8 18 4.
Boron has 3 valence electrons.Boron has 3 valence electrons.
Beryllium (Be) has 4 protons and 2 valence electrons.
4 electrons
4 electrons, 2 valence electrons
4
The period number is the same as the energy level containing the valence electrons. For example, in period 4, the valence electrons are the 4s and 4p electrons.
