How many valence electron have selenium?
6. If you look at the electron configuration of Selenium, it is [Ar]3d^10 4s^2 4p^4, meaning 10 electrons are located in the 3rd shell, and a total of 6 are located in the 4th shell, the highest energy shell. The electrons in the 4s and 4p shells combined are the valence electrons, meaning there are 6 valence electrons on Selenium.
How many electrons can 3rd shell hold?
In (3s2 3p6 3d10) = 2 + 6 + 10 = 18 electrons in the 3rd shell (3(s+p+d))
Is the outer shell of nickel full?
The outer shell of nickel is not full. Nickel has an electron configuration of 4s2 3d8, so its outer shell has two electrons which is not the maximum it can hold (which would be 8).
What is the maximum number of electrons in the second electron shell?
8 (just in the second shell) but if you're counting all of the electrons, including the first shell, then there are 10 electrons all together. Eight Electrons are the maximum.
How many valence shells does the element neon have?
Period number = no. of electron shells. Therefore neon has two shells.
How many electron shells does calcium fill?
You can calculate the total capacity of an electron shell using the formula 2n2,... electron shell, it would need 10 electrons: 2 to fill the 1st shell and 8 to fill the2nd. ... In other words, in an atom with 20 electrons (which is the element calcium
What is the maximum number of electrons that can occupy the 3rd electron shell?
3s^2 3p^6 3d^10 18 electron altogether in the third shell.
What is the maximum number of electrons in the third electron shell?
3s^2 3p^6 3d^10 18 electron altogether in the third shell.

What is the electron arrangement for calcium?
The electron arrangement for calcium is 2,8,8,2. This means that calcium has 20 electrons arranged in four energy levels, with 2 electrons in the first energy level, 8 electrons in the second and third energy levels, and 2 electrons in the fourth energy level.
How many electron shells would be completely filled by a neutral xenon atom?
A neutral xenon atom has 54 electrons. The electron configuration of xenon is [Kr] 4d^10 5s^2 5p^6, with a total of 8 completely filled electron shells (2 in the first shell, 8 in the second shell, 18 in the third shell, 18 in the fourth shell, and 8 in the fifth shell).
What does a diagram of neon look like?
I assume you wanted to know how a Neon atom is depicted. Neon is Atomic #10 meaning it has 10 protons in the nucleus. The majority of Neon atoms have 10 neutrons. This gives it an atomic mass of 10.18 AMUs. It's 1st electron shell is full with two electrons and it's 2nd electron shell full with 8 electrons. Because it's outer electron shell is full, Neon is a Noble gas meaning it is inert or non-reactive. These answers can be verified in any high school or college text book or the Merk Index.
What is the number of electrons that each energy level or electron shell needs to fill the first four electron shells?
s^2 p^6 d^10 f^14 or 1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p^6 4d^10 4f^14 Depending on what you meant.
What is the OUTER electron configuration of xenon?
im guessing you mean valence shell electron configuration that would be: 5s^2 4d^10 5p^6
How many electrons would be expected in the outer most shell of an atom with an atomic number of 10?
Given what we know about electron structure, we would expect there to be 8 electrons in the outer shell of an atom with the atomic number of 10. And that's how many there are. Element 10 is neon, and like all noble or inert gases, it has a full outer shell.There are only two electron shells for all the elements up through element 10 (neon). The first shell will only accept 2 electrons. That's the s shell, and it's the outer shell (and the only shell) for helium (the lightest inert gas). The next 8 electrons will fill the second electron shell, which is the p shell. That means element 10 (the inert gas neon) will have a full s shell (2 electrons) and a full p shell (8 electrons).
An atom with 10 electrons must have how many shells?
An atom with 10 electrons will have 2 electron shells. The first shell can hold up to 2 electrons, and the second shell can hold up to 8 electrons.
