- low atomic and mass number
- low atomic weight
- six nonmetals and two metals
litium, and elements in the 2nd period (row) are pretty common
You can discover this by looking at a periodic table of the elements.The rows of the table are called periods; the columns are called groups.The second period therefore begins with the element Lithium and ends with the element Neon.
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).
There are 114 elements in the periodic table, not just 2.
The first period is at the top of the table. It consists of hydrogen and helium. The bottom period is period 7.

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 shell model explains the organization of the periodic table. The elements in the first period have electrons in the first shell; the elements in the second period have electrons in the first two shells; the elements in the third period have electrons in the first three shells; and so on.

The elements in column 18 of a wide form periodic table or Column VIII of a narrow form periodic table, commonly called the noble gases. Also, both elements in the first period, the elements in groups 15, 16, and 17 of the second period, and the element in group 17 of the third period.
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).
A period is a horizontal row on the periodic table of the elements. There are seven periods on the periodic table. Each period corresponds to the highest energy level that contains electrons. For example, the elements in the first period have electrons in the first energy level, which is the only energy level available; the elements in the second period have their highest energy electrons in the second energy level; the elements in the third period have their highest energy electrons in the third energy level, and so on.
There are 114 elements in the periodic table, not just 2.
The first period is at the top of the table. It consists of hydrogen and helium. The bottom period is period 7.
The smallest class of the periodic table would be the semi-metals, or metalloids. The second biggest group would be the nonmetals. The largest group would be the metals.
The fourth electron shell is filled by krypton. Krypton is the last element in the fourth period on the periodic table. Each of the periods represents an electron shell. Elements in the first period have electrons in the first shell; elements in the second period have electrons in the second shell; and so on.
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.
