Identify the valence sub shell occupied by electrons in beryllium and arsenic atoms?
In beryllium (Be), the valence subshell occupied by electrons is the 2s subshell, with the electron configuration being 1s² 2s². In arsenic (As), the valence subshells are the 4s and 3d subshells, with the electron configuration being [Ar] 4s² 3d¹⁰ 4p³. Therefore, beryllium has electrons in the 2s subshell, while arsenic has electrons in the 4s and 4p subshells.
How many sodium electrons are in the second shell?
Sodium (Na) has an atomic number of 11, meaning it has 11 electrons. The electron configuration of sodium is 1s² 2s² 2p⁶ 3s¹. In the second shell, which includes the 2s and 2p subshells, there are 8 electrons (2 in the 2s and 6 in the 2p).
How does this row reflect the subshells of the second shell?
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 is the total number of subshell for sodium atom?
Oh, dude, like, sodium has 11 electrons, right? So, it's got 3 subshells: 1s, 2s, and 2p. Each subshell can hold a certain number of electrons based on some fancy rules, but who really cares about that, right? Just know that sodium's got 3 subshells chillin' in there.
What is the orbital notation of berillyum?
The orbital notation for beryllium (Be) is 1s^2 2s^2. This notation represents the distribution of electrons in the beryllium atom's electron shells and subshells.
How many subshells are there in the second energy level?
There are two subshells in the second energy level: 2s and 2p.

In arsenic (As), the valence subshells are the 4s and 3d subshells, with the electron configuration being [Ar] 4s² 3d¹⁰ 4p³. Therefore, beryllium has electrons in the 2s subshell, while arsenic has electrons in the 4s and 4p subshells.
What subshell has 8 electrons?
The third subshell, which is the 2s and 2p subshells, can hold a maximum of 8 electrons.
How many sodium electrons are in the second shell?
Sodium (Na) has an atomic number of 11, meaning it has 11 electrons. The electron configuration of sodium is 1s² 2s² 2p⁶ 3s¹. In the second shell, which includes the 2s and 2p subshells, there are 8 electrons (2 in the 2s and 6 in the 2p).

How many subshells are in the shell with n to 2?
In the shell with principal quantum number ( n = 2 ), there are two subshells: the 2s subshell and the 2p subshell. Each subshell corresponds to a different angular momentum quantum number ( l ); for 2s, ( l = 0 ), and for 2p, ( l = 1 ). Therefore, the shell with ( n = 2 ) contains a total of two subshells.
If each orbital can hold a maximum of two electrons how many electrons can 2s hold?
The 2s orbital can hold a maximum of 2 electrons.
What is the orbital notation of berillyum?
The orbital notation for beryllium (Be) is 1s^2 2s^2. This notation represents the distribution of electrons in the beryllium atom's electron shells and subshells.
How many electrons can occupy the 2s subshell and 3d subshell?
Two electrons can occupy the 2s subshell, and 8 electrons can occupy the 3d subshell.
Which of the subshells in the electron configuration of Hf behave as core orbitals?
The subshells of 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 4f act like core orbitals. This understanding of the configuration of the atom helps us to understand why electrons and atoms behave the way they do.
Rank these subshells in order of increasing energy?
1s 2s 3s 3p 4s 3d 4p
