The sum from the exponents of the blocks.For instance,
If We take the electron configuration of Sulfur (S) which is:
1s22s22p63s23p4
The total number of electrons i going to be 2 + 2 + 6 +2 + 4, which gives 16.

What is the outer electron configuration for zinc?
Valence electron configuration of zinc, abbreviated. [Ar] 4s2 3d10 Zinc's oxidation state is 2, so that 4s2 represents the valance electrons though they are at a lower energy level and the 3d10 gives you the full outer electron configuration.
What element has the electron configuration 4s2 3d7?
First, we need to add up the number of electrons in the configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10. Doing so gives a result of 30. A neutral element having 30 electrons will also have 30 protons. Checking the periodic table, we see that zinc is the element with 30 protons.
What is C- electron configuration?
1s22s22p3. Adding the exponents gives a sum of 7, which is the total number of electrons a C- ion has. Follow a diagonal rule chart and they should become easy.
Which element has the electron configuration Ne3s23p4?
Silicon.Neon has 10 electrons. Adding 4 more electrons to that gives 14 electrons, and the configuration of [Ne] 3s2 3p2. This configuration belongs to the element silicon.
What happens to an atom of magnesium when it forms an ionic bond in which it has the same electron configuration as the noble gas neon?
study island answer- It gives up two electrons
Mn electron configuration?
Manganese's atomic number is 25. Thus it has 25 electrons. Filling in the first 25 orbitals gives the electron configuration of s2 2s2 2p6 3s2 3p6 4s2 3d5.
What is the sulfer's electron configuration?
Sulfur's atomic number is 16. Thus, it has 16 protons and 16 electrons per atom. Filling in the first 16 electron orbitals gives the configuration of 1s2 2s2 2p6 3s2 3p4.
What is the electron configuration of a neutral mg?
Magnesium's atomic number is 12. Therefore, it has 12 protons and 12 electrons. Filling in the first 12 atomic orbitals gives us the configuration of 1s2 2s2 2p6 3s2.
What is the outer electron configuration for zinc?
Valence electron configuration of zinc, abbreviated. [Ar] 4s2 3d10 Zinc's oxidation state is 2, so that 4s2 represents the valance electrons though they are at a lower energy level and the 3d10 gives you the full outer electron configuration.

Electron arrangement that gives an atom stability?
An anion is an ion that has a negative charge. It is formed when valence electrons are added to the outer energy level. It is giving the ion a stable electron configuration.
What is the expanded electron configuration for es?
Einsteinium has the atomic number of 99. Thus, it has 99 protons and, to keep it neutral, 99 electrons. Filling in the first 99 electron orbitals gives us the electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f11.
How many protons are there in an atom of argon?
Argon's atomic number is 18. thus, it has 18 protons and 18 electrons. Filling in the first 18 electron orbitals gives the configuration of 1s2 2s2 2p6 3s2 3p6. Thus, argon has 3 electron energy levels.
What is the total number of valence electrons in an atom with the electron configuration 1s2 2s2 2p6 3s2 3p3?
It is element nitrogen. It has an atomic number of 7 and the valence electron is 5. It needs 3 electrons to complete its octet state. That's why sometimes it has the oxidation number of -3 in ammonia.
