Answer:
X is an element in period 3 with two electrons in the outer shell
Answer:
1 Å = 1.0 × 10⁻¹ nm
1 Å = 1.0 × 10² pm
Explanation:
Angstrom is the unit of the length which is equal to one ten-billionth of the metre or 10⁻¹⁰ m. It is represented by the symbol is Å .
Angstrom is not part of SI system of the units, but it is considered as a part of metric system.
Angstrom is used often in natural sciences as well as technology in order to express the sizes of atoms / molecules, and the lengths of the chemical bonds, etc.
1 Å = 10⁻¹⁰ m
1 nm = 10⁻⁹ m
1 pm = 10⁻¹² m
So,
1 Å = 1.0 × 10⁻¹ nm
1 Å = 1.0 × 10² pm

Answer:
the empirical formula
Explanation:
I remember learning this last year.
The correct answer that would best complete the given statement above would be option 2. <span>The relationship between molecular velocities and temperature is a direct relationship. In other words, their relationship is directly proportional. Hope that this is the answer that you are looking for. </span>
