The second period (row) on the Periodic Table consists of elements that are filling the 2nd energy level, from 2s1 in lithium to 2s22p6 in neon.

For a representative element the row number on the periodic chart will be the same as the shell number.?
True. Row number on the periodic chart will be the same as the shell number.
Why first period contains 2 elements while second period contains 8 elements?
Each row in the table contains elements that have the same number of electron orbit shells. The first orbit, which is closest to the nucleus only has space for 2 electrons (no idea why, sorry). This is why only hydrogen (1 electron) and helium (2 electrons) are in the first row. The second row has the same inner shell, with 2 electrons and an outer shell with room for 8...and so on.
How can calculate electrons in N shell?
Characterise the following 'row': 2, 8, 18, 32, 50, 72, 98 K shell has 2 L shell has 8 M shell has 18 N shell has 32 electrons
What are Cell references that reflect the row and column they have been copied to are called?
Relative Cell references
What role and column is helium in on the periodic table?
It comes second because it has the second lowest relative atomic mass (2). The reason it is on the right hand side instead of the left is because it is a noble gas and has a full outer shell of electrons.
What are atoms doing during a chemical reaction?
In an atom, there are several energy levels. However, within each energy level there are subshells. The first row of the Periodic Table (PT) has one energy level. The second row has two energy levels, and the second row has two subshells. The third row of the PT has three energy levels; the third energy level has three subshells. The outer subshell is called the valence shell, and it holds valence electrons. The first energy level can hold a maximum of two valence electrons. The second valence shell can hold 8 valence electrons. The third valence shell can hold 18. Past four the numbers get big, so we will not go there. The number of electrons that fill the valence shells determines reactivity. The Alkali Metals (first column) only need to give away 1 valence electron. The Halogens (second-to-last column) only need one to fill their outer shells. Put a Halogen and an Alkali Metal together and they will violently react in order to fill their valence shells. Atoms, in a reaction, are sharing electrons with other atoms.
How many completely full electron shells do the elements in the second row of the periodic table contain?
One, the first shell.
Will the row number on the periodic chart will be the same as the shell number?
True. Row number on the periodic chart will be the same as the shell number.
For a representative element the row number on the periodic chart will be the same as the shell number.?
True. Row number on the periodic chart will be the same as the shell number.
How many electrons can be in an electron shell?
The number of electrons depend on the principal quantum number. For n=1 the maximum number of allowed electrons is 2. And the values are 8 and 18 for n=2 and n=3 respectively. When n>3, the maximum electrons allowed in the shell is 32.
How many shells are in an element in the sixth row of the periodic table?
6 shells. The first row on the periodic table has 1 shell The second row has 2 shells The third row has 3 shells ... The seventh row has 7 shells. You get the idea :)
What creature has a row of eyes around its shell?
Llamas. With a shell. That has eyes around it.
What is the outer shell of first row of periodic table?
K shell (or 1s orbital).
Why first period contains 2 elements while second period contains 8 elements?
Each row in the table contains elements that have the same number of electron orbit shells. The first orbit, which is closest to the nucleus only has space for 2 electrons (no idea why, sorry). This is why only hydrogen (1 electron) and helium (2 electrons) are in the first row. The second row has the same inner shell, with 2 electrons and an outer shell with room for 8...and so on.
Does bench seat fit in the second row?
The bench seat is the second row!!
What is the determinant of a two-by-two matrix?
To find that, you multiply the first element of the first row by the second element of the second row. You also multiply the first element of the second row with the second element of the first row. Then you subtract the products not add them.
What is the transpose of a matrix?
Take each row and convert it into a column. The first row becomes the first column, the second row, the second column, etc.
