What element has an atom with the electron configuration 2 8 8 2?
calcium
The electronic configuration of calcium is 2, 8, 8, 2 .
What element has the electron configuration of 2/8 3?
Aluminum
The element with the Electron Configuration (2,8,3) is Aluminum as it has the atomic number 13.
What ion has an electron configuration of 2/8 8?
Ca has electronic configuration 2,8,8,2 and when it forms Ca2+ ion it loses 2 electrons and so its electronic configuration will be 2,8,8.
Which element has the electron configuration of 2/8 6?
Sulfur
Sulfur (16S) has a total of 16 electrons (2+8+6=16), and the atomic number of Sulfur is “16”. Sulfur is placed in the periodic table in place of 16 groups and 3 periods.
What is the atomic number of this element 2 8 8?
Atomic Number of Element is 20 Given, Electronic Configuration (2, 8, 8, 2) which makes the Atomic Number as 2 + 8 + 8 + 2 = 20.
Is 2 8 3 a ground or excited state configuration?
Ground state electron configuration of aluminium is Al-2-8-3 as we see on the picture. One example of an excited state configuration: Al-2-7-4. In this example one electron “jumped” from the second shell to the third shell which is higher in energy.
Which element has the electron configuration 2 8 7?
chlorine
⇒ 2+8+7 = 17. Therefore, the atomic number of this element is 17 and the element is chlorine. It would be chemically similar to F(9) with configuration as 2, 7.

What is the valency of an element with electronic configuration 2 8 7?
The electronic configuration of chlorine can be written as 2, 8, 7. 2, 8, 7 electrons are distributed in the shells K, L, M respectively. Therefore, valence electron in chlorine is 7 and it needs to gain 1 electron from the outermost orbit to attain octet. Hence, the valency of chlorine is 1.
What is the atomic number of the element with electronic configuration 2 8 2?
The atomic number of this element is 12.
