B is the correct answer, thankyou.
Sodium Na is a soft, low-density member of the alkali metal family. The element sodium is a very delicate silvery-white.
Sodium makes up 2.8 percent of the Earth's crust and is the most prevalent alkali metal and sixth most plentiful element on the planet.
A metal is a substance that has a shiny look when freshly processed, polished, or shattered, and conducts electricity and heat rather effectively. Typically, metals are malleable and ductile.
Ionic linkages mix metals with non-metals, whereas metallic connections happen between metal atoms. The metallic bonding joins metal atoms.

The volume of a 0.40 M Mg(NO3)2 solution contains 89g of Mg(NO3)2 is 1.5 L.
Solution is defined as a particular kind of homogenous combination made up of two or more different ingredients. Solute refers to the material that dissolves. Solvents are described as substances that do not dissolve. The substance known as salt water is a solution. A solute and a solvent combine to produce a solution; this is a physical, not a chemical process. A solution is produced when one substance splits apart or dissolves into another.
To calculate this, subtract 89g from 148.3g/mol, the molar mass of magnesium nitrate.
= 89 / 148.3
= 0.6 mole of magnesium nitrate
The volume of solution can be as
= 0.6 moles / 0.40 M
= 1.5 liter.
Thus, the volume of a 0.40 M Mg(NO3)2 solution contains 89g of Mg(NO3)2 is 1.5 L.

Nitrogen has three occurring isotopes: Nitrogen-13, Nitrogen-14, Nitrogen-15.
The most abundance isotope is nitrogen-14 because of its stability and resistance to radioactive decay.
Isotopes are variants of a chemical element that have the same number of protons (which defines the element) but a different number of neutrons in their nuclei. This means that isotopes of the same element have slightly different atomic masses. In the case of nitrogen, its three naturally occurring isotopes are nitrogen-13 (N-13), nitrogen-14 (N-14), and nitrogen-15 (N-15).
The abundance of an isotope refers to the percentage of that isotope present in a naturally occurring sample of the element. The different isotopes of an element are usually found in different proportions, and the most abundant isotope is the one that appears most frequently in nature.
Nitrogen Isotopes:
a) Nitrogen-14 (N-14):
Nitrogen-14 is the most abundant isotope of nitrogen. It has 7 protons and 7 neutrons in its nucleus. N-14 makes up about 99.63% of naturally occurring nitrogen. This high abundance is primarily due to the relatively stable nuclear configuration of N-14, making it less prone to radioactive decay.
b) Nitrogen-15 (N-15):
Nitrogen-15 is the second most abundant isotope of nitrogen. It has 7 protons and 8 neutrons in its nucleus. N-15 makes up a much smaller percentage of naturally occurring nitrogen, around 0.37%. While N-15 is less abundant than N-14, it is still significant and plays a role in various scientific and environmental studies.
c) Nitrogen-13 (N-13):
Nitrogen-13 is the least abundant of the three naturally occurring nitrogen isotopes. It has 7 protons and 6 neutrons in its nucleus. N-13 is radioactive and is not as stable as N-14 and N-15.
The higher abundance of nitrogen-14 can be attributed to its relative stability compared to the other isotopes. The number of neutrons in an isotope's nucleus affects its stability, and N-14 has a balanced number of neutrons to maintain its stability. This stability prevents it from undergoing radioactive decay at a significant rate, allowing it to persist in higher proportions in nature.
