Explanation:
Helium has two electrons in its energy shell, while argon and neon have 8 electrons in their valence shells. As these have maximum number of electrons in their valence shells, they do not have any tendency to combine with other elements. Hence, they have a valency equal to zero.
<h2>Standart Deviation Steps:</h2>
1. Work out the mean (the simple average of the numbers).
2. Then for each number: subtract the mean and square the result.
3. Then work out the mean of those squared differences.
4. Take the square root of that.
<h2>Result:</h2>
Number of Elements in Array: 5
Series Average: 34,748
Median: 34,795
Smallest Number: 34,53
Biggest Number: 34.86
Standard Deviation: 0.12716131487209
Variance (Standard Deviation): 0.01617
Standard Deviation of the Population: 0.1137365376649
Variance (Standard Deviation of Population): 0.012936
Answer:
Magnesium also reacts with nitrogen in the air to produce some magnesium nitride (Mg3N2). Safety: Do not look directly at the burning magnesium due to the intensity of the light. A dry-powder fire extinguisher should be available. Disposal: Once cooled the solid magnesium products can be thrown in the trash.

Explanation:
Hello there!
In this case, since the density of the metal is computed as shown below:
We need to calculate the volume of the solid by subtracting the final volume and the initial volume of water:
Thus, we obtain:
