Lava that cools so quickly that ions do not have time to arrange themselves into crystals will form igneous rocks with a
a. porphyritic texture.
b. coarse-grained texture.
c. glassy texture.
d. fine-grained texture.

Option (D)

Explanation: Magmas when comes out of the surface, then it is known as lava and this lava immediately solidifies, and forms igneous rocks. The crystal's size and texture depends upon the rate of cooling of magma.

Thus the correct answer is option (D).

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.

the answer is na (sodium)
