a. mafic minerals contains lower levels of iron and magnesium.

b. mafic minerals contain more dark-colored, high-density minerals

c. mafic minerals contain more light-colored, low-density minerals.

d. mafic minerals contain higher levels of feldspar and quartz

Mafic minerals contain more dark-colored, high-density minerals.

Explanation:

Mefic and felsic minerals represent two kinds of minerals or lava.

For example, mefic lava is more viscous than felsic lava.

The other difference is that word mafic is related to presence of Magnesium and iron minerals more while in felsic (Feldspar) silica content is more.

Mefic minerals are associated with dark color while felsic are lighter in color.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
