What element has 2 electrons in its outer shell and 12 in total?
Magnesium. The complete electron configuration is: 1s2 2s2 2p6 3s2 The complete electron arrangement is: 2e, 8e, 2e
How many electrons are in the second principal energy level for Clorine?
Chlorine has 17+ Prontons & 17- Electrons Energy levels go 2e - 8e - 18e - 32e So Chlorine has 2 in the first shell which leaves 15 (17e-2e = 15) So that means 8 in the second shell which leaves 7 (15e-8e = 7) That leaves 7 in the third shell The answer is 8 Anything with 10 or more electrons or an atomic # 10 or more would have 8 for the second shell.
What is the bohr Rutherford diagram of sodium?
The Bohr-Rutherford diagram of sodium consists of a nucleus with 11 protons and 12 neutrons, surrounded by two electron shells. The first shell contains 2 electrons and the second shell contains 8 electrons. Sodium has one electron in its outermost shell, which makes it reactive and likely to form ions.
Draw an electron shell diagram of the ionic compound calicum oxide CaO?
Calcium has 2 valence electrons while oxygen has 6 valence electrons. When adding calcium and oxygen together, they form calcium oxide or CaO, and calciums 2 valence electrons join with oxygens 6 to fill the Lewis structure. Ca 2+ [O with 8e-] 2-

the electron dot structure for lithium is Li ' (the element symbol with one dot on the upper right side)
What is the exponential notation for 2x2x2?
2e+0 x 2e+0 x 2e+0 = 8e+0
What is the name of a element that has 17 neutrons and a mass of 32?
that's easy. 32 neutrons means that the mass of protons is 25 (as is the electrons) so all i have to do is look for the right one. simlpy thinking there are 2e (2 electrons on te inner shell) ten each one afterwards has up 8e unless there are no more electrons to fill the shell. in this case its like this: 2e, 8e, 8e, 7e. the element is infact manganese in group 5 (Mn). magnese will react with anything from group one easily at a 1:1 basis and will react with anything from group 2 at a 2:1 basis (the 2 representing magnese).
