In what type of orbital is the outermost electron in NA?
3s orbital
For example, sodium (Na), which has a single electron in its outer 3s orbital, can lose that electron to attain the electron configuration of neon. Chlorine, with seven valence electrons, can gain one electron to attain the configuration of argon.
How many electron shells does a Na atom have?
List of elements with electrons per shell
Z | Element | No. of electrons/shell |
---|---|---|
9 | Fluorine | 2, 7 |
10 | Neon | 2, 8 |
11 | Sodium | 2, 8, 1 |
12 | Magnesium | 2, 8, 2 |
How many orbits are there in sodium ion?
When we write the configuration we’ll put all 11 electrons in orbitals around the nucleus of the Sodium atom. In writing the electron configuration for sodium the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for sodium go in the 2s orbital.
What is the orbitals of sodium?
In this notation, the electronic configuration of sodium would be 1s22s22p63s1, distributed in the orbitals as 2-8-1. Often, a shorthand method is used that lists only those electrons in excess of the noble gas configuration immediately preceding the atom in the periodic table.
Which is the outermost shell of Na atom?
The outermost shell of the sodium ion is the second electron shell, which has eight electrons in it.
How many electrons does Na+ has in its outermost shell?
eight electrons
The properties of Na+ ion and the sodium atom are different from each other. The positive charge dictates all the properties of Na+ , since otherwise it is stable and inert with its eight electrons in the valence shell.
How many electrons does B have?
2,3Boron / Electrons per shell
How many electrons in a sodium atom are in the N 3 state atomic number of sodium 11?
This means that sodium atoms have eleven protons in their nucleus and eleven electrons orbiting it. Since the maximum number of electrons that can be in the 1n shell is two and the maximum number of electrons that can be in the 2n shell is eight electrons, sodium atoms have a 3n shell with one electron.
What type of element is na?
sodium (Na), chemical element of the alkali metal group (Group 1 [Ia]) of the periodic table. Sodium is a very soft silvery-white metal….sodium.
atomic number | 11 |

How many unpaired electrons are there in Na+?
The electronic configuration of Sodium(Na) is 1s2 2s2 2p6 3s1. In 1s, 2s and 2p orbitals have two electrons so they are paired but in 3s orbital only one electron is present so Sodium has one unpaired electron.
How many electrons in Na are in the 2nd shell?
So, sodium’s 11 electrons are arranged this way: 2 electrons in the first “shell”, 8 electrons in the second “shell”; and 1 electron (the valence electron) in the third “shell”. We write this as 2.8. 1. The last number is how we know the number of valence electrons.
