Question

What does a 2s orbital look like?

Answer 1

spherically symmetric around the nucleus

Answer 2

Answer:

The "s" tells you about the shape of the orbital. s orbitals are spherically symmetric around the nucleus - in each case, like a hollow ball made of rather chunky material with the nucleus at its center. ... 2s (and 3s, 4s, etc) electrons spend some of their time closer to the nucleus than you might expect.
