The allowed orbital types for the second period of the periodic table are 2s and 2p.
For n=2, you can have only s and p orbitals, hence all elements in this period are either in s-block or p-block.
Lithium is in the second period and the first group in the Periodic Table of Mendeleev.
fluorine
The first period is at the top of the table. It consists of hydrogen and helium. The bottom period is period 7.
Eight. In order as would be seen in the second period on the periodic table, they are Lithium (Li), Beryllium (Be), Boron (B), Carbon (C), Nitrogen (N), Oxygen (O), Fluorine (F), and Neon (Ne).
For n=2, you can have only s and p orbitals, hence all elements in this period are either in s-block or p-block.
Groups 1 & 2 (1st and second column in the periodic table)(:
The second period. (Rows)
Boron has 2 shells altogether. 2 electrons on the first one and the remaining three on the second. Altogether boron (B) has 5 electrons.
Lithium is in the second period and the first group in the Periodic Table of Mendeleev.
A wave or other periodic phenomenon with a period of 1 second has a frequency of 1 Hz.
The first three periods of the periodic table are called the first period, second period, and third period.
fluorine
Every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons. It goes down the periodic table like that. This also means that the atomic weight of the elements gets larger and larger in each period.
The orbital period of Saturn is 29.4571 years. Its orbital velocity is 9.69 kilometers per second and the orbital path is about 9 billion kilometers.
Nitrogen (denoted N) is in the second period and in the fifteenth group.A period is a row in the periodic table.It is referred as an period because the elements (in this case: Li, Be, B, C, N, O, F, Ne) have similar properties between them. For those that have an greater understanding (or desire) of chemistry, each element in the second period have an 1s, 2s, and 2p orbitals.Refer to your copy of your periodic table for a better comprehension.

The first period is at the top of the table. It consists of hydrogen and helium. The bottom period is period 7.
