How many electrons in an atom can have each of the following quantum number or sublevel designations?
Karo-lina-s [1.5K]

Answer: (a) 2 (b) 6 (c) 14

Explanation:

In the Azimuthal quantum number(l) electrons in a particular subshell (such as s, p, d, or f) are defined by values of l (0, 1, 2, or 3).

s is l=0, p is l=1, d is l=2, f is l=3.

The magnetic quantum number (ml)  The value of ml can range from -l to +l, including zero. Thus the s, p, d, and f subshells contain 1, 3, 5, and 7 orbitals each, with values of m within the ranges 0, ±1, ±2, ±3 respectively. Each shell can have 2 x l + 1 sublevels, and each of these sublevel can accommodate up to two electrons.

(a) n=2, l=1, ml=0. If l=1 then 2 x 1+ 1=3 sublevels, 3*2=6 electrons. When l=1, ml =-1,0,+1, ml=0  accommodate two(2)electrons

(b) 5p. p is l=1  If l=1 then 2 x 1+ 1=3 sublevels, 3*2= electrons. This means in the 5 shell, the p orbital has 3 subshell and accommodate 6 electrons.

(c) n = 4, l = 3 if l=3 then 2 x 3+ 1=7 sublevel 7*2=14 electrons. This means the in the 4 shell, the f orbital has 7 subshell and accomdate 14 elections.

Which of the following are held together by nonpolar convalent bonds?
Olin [163]

A. Atoms of chlorine (Cl)

Explanation:

The atoms of chlorine are held together by non-polar covalent bonds.

  • Covalent bonds are formed between two or more atoms having zero or very small electronegativity difference.
  • For homonuclear molecules where the two bonding atom are of the same kind, the electronegativity difference is zero.
  • This covalent bond type is called non-polar covalent bond.
  • In this bond type, there is equal sharing of the electron pair between the atoms and there is no electrostatic charge on the molecule.
