Which statement best explains why hydrogen's atomic number is equal to its mass? (1 point) O Hydrogen is in the first row and the first column of the periodic table.
O Hydrogen has one electron and one proton.
O Hydrogen does not have any neutrons.
O Hydrogen is stable, with two electrons in its outer shell.

We have that The Mass atomic number is equal to its mass number of Hydrogen because it bears no Neutrons .

O Hydrogen has one electron and one proton.

Explanation:

The hydrogen atom is composed of one proton in the nucleus and one electron, which moves about the nucleus. In the quantum theory of atomic structure, it is assumed that the electron does not move in a well-defined orbit. Instead, it occupies a state known as an orbital, which may be thought of as a “cloud” of negative charge surrounding the nucleus

explanation:

crosscutting concepts have application across all domains of science. as such, they are a way of linking the different domains of science. they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.
