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.
What else can I help you with?
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.
What are Cell references that reflect the row and column they have been copied to are called?
Relative cell references reflect the position relative to the original cell when copied to a new location.
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 is the electron configuration for 1s22s22p63s23p64s2?
I believe its Boron.1s2 2s2 2p1 --> 5 electrons. Boron is atomic number 5, so 5 protons and 5 electrons balance. Look at the Periodic table. The first row (period) corresponds to the first level of electron shell (1s). The second row corresponds to the second shell (2s & 2p). Shell 2s is Lithium and Beryllium on the far left, then 2p for the groups (columns) on the right hand side. It 'jumps' with a gap, because lower shells fill up faster (2p has a maximum of 6 electrons, which when full is Neon - a noble gas will a full shell)
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 many completely full electron shells do the elements in the second row of the periodic table contain?
One, the first shell.
How many electrons are in the outer shell of the atom of the elements in the second and third rows of the periodic table?
The second and third energy levels of an atom each contain 8 electrons. That is why there are eight elements on the second row (Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, and Neon) and third row (Sodium, Magnesium, Aluminum, Silicon, Potassium, Sulfur, Chlorine, and Argon) of the periodic table.
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.
What creature has a row of eyes around its shell?
Llamas. With a shell. That has eyes around it.
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.
What is the outer shell of first row of periodic table?
K shell (or 1s orbital).
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.
Does bench seat fit in the second row?
The bench seat is the second row!!
What tells how many energy levels an atom has?
The number of energy levels an atom has is determined by the period or row it occupies in the periodic table. Each row corresponds to the number of electron shells an atom possesses, with the first row having one shell, the second row having two shells, and so on.
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 determines where one row ends and another begins in the periodic table?
The row in the periodic table is determined by the principal quantum number (n) of the element's electrons, which represents the energy level or shell that the electrons occupy. Each row corresponds to a different principal quantum number, with the first row corresponding to n=1, the second row to n=2, and so on.
