Scoria
Explanation:
Scoria is a rock that is commonly made up of gas bubbles and minerals such as hornblende, muscovite, olivine, lucite and or plagioclase.
Scoria is an extrusive igneous rock with a lot of cavities and vesicles indicating gas bubbles.
- Scoria is product of basaltic magma.
- It has nearly the same composition as basalt since it originates from it.
- They silica deficient and very fine grained with holes in them.
- The holes shows channels by which trapped gases are forcefully ejected out.
- They are usually found associated with cindercone volcanoes.

Hey there!
Na is sodium, which has 11 protons.
The more realistic amount of neutrons for this atom to have is 12. 23 would be the sum of protons and electrons.
The atom has a charge of 1+, so there is one less electron than protons, so
11 - 1 = 10 electrons.
Your answer is d. it has 11 protons, 10 electrons, and 12 neutrons.
Hope this helps!
