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 electrons can occupy the 2s subshell and 3d subshell?
Two electrons can occupy the 2s subshell, and 8 electrons can occupy the 3d subshell.
How many subshells are there in the second energy level?
There are two subshells in the second energy level: 2s and 2p.
What subshell has 8 electrons?
The third subshell, which is the 2s and 2p subshells, can hold a maximum of 8 electrons.

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.

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
What is the maximum number of electrons the first energy level will hold?
The number of electrons in the lowest electron shellis2 in the first or K shell (subshell 1s)---For other shells, the maximum is determined by the formula 2n2:2) 8 in the L shell (subshells 2s, 2p)3) 18 in the M shell (subshells 3s, 3p, 3d)4) 32 in the N shell (subshells 4s, 4p, 4d, 4f)5) 50 in the O shell (subshells 5s, 5p, 5d, 5f, 5g*)6) 72 in the P shell (subshells 6s, 6p, 6d, 6f, 6g, and an unnamed subshell)7) 98 in the Q shell (subshells 7s, 7p, 7d, 7f, 7g, and two unnamed subshells)* the highest existing subshells are 5f, 6d, and 7s* the highest currently predicted subshells are 7p and 8s* no existing element has more than 32 electrons in any shellThe maximum per subshell is determined by the formula 2(2L+1) (s is 0):s subshells can have 2 electronsp subshells can have 6 electronsd subshells can have 10 electronsf subshells can have 14 electronsg subshells can have 18 electrons*There are no elements with electrons past the f subshell, so the shells with 22 and 26 electrons have no name. The largest element created (Roentgenium, element 111) has 2 electrons in the 7s shell.
How many electrons are present in the N shell of potassium?
There are 19 electrons present in the N shell of potassium. Potassium has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s1. The electrons in the N shell include those in the 2s, 2p, 3s, and 3p subshells.
Actually carbon valency written as 1s2 2s2 2p2.why not this is write as 1s2 2s1 2p3?
First of all this is not Carbon's valency, it is electronic configuration or arrangement of electrons around nucleus. Electron filling takes place by Aufbau principle. Explanation: Electrons around an atom are arranged in shells( denoted by n) numbered 1, 2, 3, and so on. Each of these shells is further divided into s,p,d,f subshells(denoted by l). It is known that electrons in a subshell have same energy. Electron filling occurs 1st in subshells of lower energy and higher energy subshell is filled only after the lower subshell is completely filled (Aufbau principle). Subshell whose n+l sum is less has lower energy. So here 2s(n+l=2) shell is lower to 2p(n+l=3), and 2s can have 2 electrons so after 2s is filled 2 electrons left go to 2p subshell.
