An element has an electron configuration of 1s22s22p63s2 Which of these will be in the same group as this element?
1s2 2s2 2p6 3s2 3p 4s2
What element has the electron configuration 1s22s22p63s2?
That's correct! Sulfur (S) is in the third row, so it has electrons in the third energy level. The first two levels are completely filled, giving 1s22s22p6 and it has six electrons in the third level, giving 3s23p4.
What element has the electron configuration of 1s2 2s2 2p6 3s2 3p5?
That element is chlorine (Cl). You can tell for two reasons: first, the second number in each section (which, when properly written, is a superscript) should all add up to the element's atomic number. Another reason is that the configuration ends in 3p5, which tells you that the element is in period 3, and it's one spot back from the noble gas, which automatically will end in 3p6. The noble gas is argon (Ar), so the element in question must be chlorine.
Electron configuration of Mg?
1s2, 2s2 2p6, 3s2 In my class Mg would be written (level 1, 2, 3, ..) as 2, 8, 2 Energy Level => Max numbers of electrons is 1 => 2 2 => 8 3 => 18 4 => 32
What is magnesium's highest occupied energy level?
Magnesium is 1s22s22p63s2 and so the 3rd energy level is the highest occupied level.

What is the electron configuration of an element?
The electron configuration of an element shows the number of electrons in their energy levels and orbitals. For example, the electron configuration of a neutral magnesium atom, Mg, with 12 electrons, is 1s22s22p63s2. This means that there are two electrons in the s orbital of the first energy level, two electrons in the s orbital and six electrons in the p orbital of the second energy level, and two electrons in the s orbital of the third energy level. The number in front of each letter represents the energy level, the letter represents the orbital, and the superscripts represent the number of electrons in the orbital.
What is magnesium's highest occupied energy level?
Magnesium is 1s22s22p63s2 and so the 3rd energy level is the highest occupied level.
