As Principle Quantum Number is 7, so the number of Azimuthal Quantum Numbers for this energy level is calculated by following formula,
l = n - 1
As, n=7
So,
l = 7 - 1
l = 6
So, n=7 contains 1, 2, 3, 4, 5 and 6 Sub-Shells.
Number of Electrons in Subshells,
Number of electrons in each subshell is calculated by following formula,
2 (2l + 1)
As, l=1 (given),
So, 2 (2(1) + 1)
2 (2 + 1)
2 (3)
6
Result:
The number of electrons in n=7 and l=1 are 6.
Answer:
3 electrons are gained by one nitrogen atom in the formation of K₃N.
Explanation:
The reaction is as follow,
<span> 6 K + N</span>₂<span> </span>→ <span> 2 K</span>₃<span>N
</span>
Oxidation of K,
K → K⁺ + 1 e⁻
Or,
6 K → 6 K⁺ + 6 e⁻
In oxidation reaction potassium atom transfers one electron per atomn and six electrons per six atoms.
Reduction of N;
N₂ + 6 e⁻ → 2 N³⁻
In reduction reaction one molecule of N₂ gains six electrons and 3 electrons per one atom
1/8 got it from Yahoo answers and the answer was highlighted with 4 likes.... so most likely thats it
Answer:
Molarity = 0.5 M
Explanation:
Given data:
Mass of NaCl = 2.7 g
Volume = 100 mL(100×10⁻³L)
Molarity of solution = ?
Solution:
Formula:
Molarity = number of moles / volume in litter
Number of moles:
Number of moles = mass/ molar mass
Number of moles = 2.7 g/ 58.5 g/mol
Number of moles = 0.05 mol
Molarity = number of moles / volume in litte
Molarity = 0.05 mol / 100×10⁻³L
Molarity = 0.5 M
This is because it has a full outer valence shell! so there are 8 electrons and that means it doesn't have the urge the gain anymore
