Question

Which statement about metals and nonmetals is correct?(1 point)

Answer 1

Which statement best explains why hydrogen’s atomic number is equal to its mass?(1 point)

Answer 2

Use the periodic table to answer the question.

Answer 3

Both metals and nonmetals can conduct electricity, but metals are generally malleable and nonmetals are generally brittle.

Answer 4

The statement that best explains why hydrogen's atomic number is equal to its mass is that hydrogen has only one proton in its nucleus, and since the atomic number represents the number of protons in an atom, it is equal to the mass of a hydrogen atom.

Answer 5

I apologize for the confusion. The periodic table provides more detailed information regarding the elements, including their atomic number and atomic mass. In the case of hydrogen, its atomic number is 1, indicating that it has one proton. However, its atomic mass is 1.008, which is slightly greater than 1. This is because hydrogen can exist as different isotopes with varying numbers of neutrons, resulting in slightly different atomic masses. Therefore, the original statement that hydrogen's atomic number is equal to its mass is not correct.
