WebNov 4, 2024 · Here is a table of element valences. Remember that an element's electron cloud will become more stable by filling, emptying, or half-filling the shell. Also, shells don't stack neatly one on top of another, so don't always assume an element's valence is determined by the number of electrons in its outer shell. WebMar 24, 2024 · Number of electrons in shells. Thus, 1st shell can hold 2 electrons. 2nd shell can hold 8 electrons. 3rd shell can hold 18 electrons. 4th shell can hold 32 electrons. Now the atomic number of Sodium (Na) is 11. Hence sodium element has the electrons arrangement 2, 8, 1.
How many electrons does sodium have in its outer shell?
WebThat means there are 11 electrons in a sodium atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and only one in shell three. More … WebOct 22, 2024 · The sodium atom has a total of 11 electrons, so we have to put 11 electrons in orbitals. The first two electrons will go in the 1s orbital as S orbital can hold a … costumes in cagayan valley
