This information is correct. This is because the order of classification is domain, kingdom, phylum, class, order, family, genus, species. Since class comes before family, the two organisms could be in the same class, but then when you specify further, they could be in different families.
Answer: Heyo Kenji Here! Here's your answer- Mg =1s2 2s2 2p6 3s2 = [Ne]3s2, therefore magnesium has 10 core electrons from its 1s2, 2s2, 2p6 orbitals. Magnesium is element 12, so it has 12 protons and a nuclear charge of 12.
Explanation: Hope this helps!
Have a nice day!

Answer:
A.) NF₃
D.) ClO₃⁻
Explanation:
To determine the molecular shape of the molecules, you need to:
1.) Calculate the total valence electrons in the molecule
-----> The sum of the element's valence electrons
2.) Draw the Lewis structure
Answer:
2 significant figures.
Explanation:
Significant Figures Rules:
1. Anything that isn't a zero is a sig fig
2. If a decimal point comes after the ones digit, everything before the decimal is counted as sig fig (i.e 2000. would be 4 sig figs).
3. If we are dealing with small decimals, the zero before and after the decimal (i.e 0.002) is a placeholder and is not counted as sig figs.
4. Any zeros between 2 significant digits is considered in sig figs (i.e 2002 would be 4 sig figs)
Since we are dealing with 87000, we see that we have no decimal point. That means our only sig figs are 8 and 7, which equals 2 sig figs.
