Answer:
<em>The ionic radius is the the distance from the nucleus to the outermost electrons in a ion. While the atomic radius is the distance from the nucleus to the normal valence electrons.The ionic radius is half the distance between two gas atoms that are just touching each other. If the atom loses its outermost electron (positively charged or cation), the ionic radius is smaller than the atomic radius because the atom loses an electron energy shell.</em>

Answer:
2.10x10⁻⁹ moles of Si, 143.7 moles of CCl₄, 3.49x10²⁴ atoms
Explanation:
These is the relation:
NA (6.02x10²³) ⇒ 1 mol of particles (it can be, atoms or molecules)
This are the rule of three:
NA of atoms occupies 1 mol of Si
1.27x10¹⁵ atoms will occupy (1.27x10¹⁵ .1 ) / NA = 2.10x10⁻⁹ moles of Si
NA of molecules are contained in 1 mol of CCl₄
8.65x10²⁵ molecules are contained in (8.65x10²⁵ .1)/ NA = 143.7 moles
1 mol of Ca has NA atoms
5.80 moles of Ca will have (5.80 . NA) = 3.49x10²⁴
Explanation:
High carbon concentration in the deep ocean means increased absorption of carbon to the atmosphere resulting to even greater and harmful amounts of carbon in the atmosphere. Therefore we need to keep a close eye of the deep ocean in the quest to monitor and pump out excess carbon from this part of marine life.
The sum of protons and neutrons in an atomic nucleus would be the MASS NUMBER.
I think the answer is A or anything with Barometer
