Answer:

20.7 g NH3

Explanation:

<u>Convert to moles of N2:</u>

(17.0 g N2) / (28.02 g/mol N2) = 0.607 moles N2

<u>Convert to moles of NH3: </u>

(0.607 moles N2)(2 moles NH3 / 1 mole N2) = 1.213 moles NH3

<u>Convert to grams of NH3:</u>

(1.213 moles NH3)(17.03 g/mol NH3) = 20.66 g NH3

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.

How are elements similar to those in the same group on the periodic table ​
enot [183]

Answer:

All the members of a group of elements have the same number of valence electrons and similar chemical properties.

Explanation:

The vertical columns on the periodic table are called groups or families because of their similar chemical behavior.
