Boron is to the immediate left of carbon in the same row in the periodic table. Which of the following statements compares the radius and pull exerted by the protons of boron and carbon atoms? A. Boron has a smaller radius and the protons in carbon exert a greater pull.
B. Boron has a larger radius and the protons in carbon exert a greater pull.
C. Boron has a smaller radius and the protons in carbon exert less pull.
D. Boron has a larger radius and the protons in carbon exert less pull.

Boron has a larger radius and the protons in carbon exert more pull.

Explanation:

Remember than elements have greater radius as they are closer to the bottom left corner, so boron would have the larger radius here. Carbon has a smaller radius, which makes it easier for the protons in carbon to exert more pull.

Boron has a larger radius and the protons in carbon exert more pull.

Explanation:

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
