Two atoms each have 14 neutrons. The first has 13 protons and 13 electrons and the second has 14 protons and 14 electrons. Are these atoms isotopes of the same chemical element? Why?

Explanation:

Nope both atoms aren't isotopes of same chemical elements.. In isotopes both atom should have same number of protons or atomic number with different mass number, but here it's 13 and 14 protons so different atomic number

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.

explanation:

it would be a gas formation
