What element has an electron configuration of 2 8 8 1?
Potassium.
What electron could have quantum numbers n 2 l 1 m?
L-1 electron configuration
What ions does not have the same electron configuration as the noble gas neon a o minus 2 b f minus c al plus 3 d s minus 2 e mg plus 2?
D. S-2Electron configuration has to do with the number of electrons, so using a Periodic table, it is easy to find this answer.For example, O-2 has 2 more electrons than usual, so move two spaces to the right, which is neon.For F- , it is the same way. Since it is a minus 1, move one space to the right, which is neon.For Al+3 there are 3 LESS electrons than usual so move back(to the right) 3 spaces, which is neon.For S-2 , the answer to your problem, has the same electron configuration as Argon.For Mg+2 there are 2 less electrons so moving back 2 spaces gives you neon.Remember 'minus' means more electrons so for electron configurations you move forward on the Periodic table for ions with negative charge and backwards if the ion is positive.
How many is 2 x 2?
2*2 is 4. like 2+2=4
What is 2 sqared?
It is like this if you are doing 2 squared you do 2 *2 = 4
