What else can I help you with?
An element in the second row of the rare earth elements in the periodic table are?
litium, and elements in the 2nd period (row) are pretty common
How many elements are there in the second period of the periodic table?
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).
How many elements occur in each of the first three periods or the periodic table?
There are 2 elements in the first period, 8, 8 elements in 2nd and 3rd periods respectively,
What are the allowed orbital types for the second period of the periodic table?
The allowed orbital types for the second period of the periodic table are s and p orbitals. This means that elements in the second period can have a maximum of 2 electrons in an s orbital and 6 electrons in p orbitals.
What is second period at the bottom of the periodic table called?
The first period is at the top of the table. It consists of hydrogen and helium. The bottom period is period 7.

The first period is at the top of the table. It consists of hydrogen and helium. The bottom period is period 7.
What group of elements in the periodic table is made up of elements that are gases at room temperature?
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.
What are the elements in the second period of the periodic table of elements?
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.
Period in chemistry?
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.
What do periods and groups have in common in a periodic table?
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.
What is the smallest class of the periodic table?
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.
What are three elements in the same period?
H and He are in the first period. Li Be, B, C, N, O, F, Ne are in the second and so on. A period is one row across on the periodic table
From left to right across the second period of the periodic table?
The second period of the periodic table contains elements from lithium to neon, in increasing atomic number order. These elements have increasing numbers of protons and electrons as you move from left to right across the period, resulting in changes in properties such as atomic size and reactivity.
