5. Which of the following statements about the compound HCI is true? (1 point)

A. the physical and chemical properties of HCI are different from those of H2 and CI2.
B. only the physical properties of HCI are different from those of H2 and CI2.
C. only the chemical properties of HCI are different from those of H2 and CI2.
D. the physical and chemical properties of HCI are the same as those of H2 and CI2.

Answer 1

Atoms of different elements have different numbers of protons and neutrons in their nucleus. More importantly, they have different numbers of electrons around the nucleus. It is the interaction of the orbiting electrons with those of other atoms that give rise to the various chemical properties of different elements.

Answer 2

so 1 is probably all of the above

Answer 3

What about number 2?

Answer 4

im thinking it could be C im not sure though

Answer 5

@Destinymasha

Answer 6

2 - 8 proton and 8 neutrons
