Answer is: it is not possible, because orbital (azimunthal) quantum number cannot be 2.
The principal quantum number (n) is one of four quantum numbers which are assigned to each electron in an atom to describe that electron's state.
For principal quantum number n=2:
1) azimuthal quantum number (l) can be l = 0...n-1:
l = 0, 1.
The azimuthal quantum number determines its orbital angular momentum and describes the shape of the orbital.
2) magnetic quantum number (ml) can be ml = -l...+l.
ml = -1, 0, +1.
Magnetic quantum number specify orientation of electrons in magnetic field and number of electron states (orbitals) in subshells.
3) the spin quantum number (ms), is the spin of the electron.
ms = +1/2, -1/2.
Answer: 1.005919176541433
Explanation:
C) S
Because of the trends of electronegativity. Increases across a period and decreases down a group.
The answer is (2). To calculate the density, you need to divide the mass with volume. When doing division, the significant figures of result is the minimal of the numbers using before. So the answer is 2.
