Answer:
Answer in explanation
Explanation:
The reactivity or passiveness of an element depends solely on how close it is to attain a noble gas configuration. This means the closer an element is to attain a noble gas configuration, the greater its reactivity in both direction, positively or negatively.
Alkali metals belong to group 1 of the periodic table while halogens belong to group 17 of the periodic table. This means they are just one electron away from achieving the stability of a noble gas configuration. While alkali metals need to lose one electron to form a univalent positive ion, halogens news to gain one electron to form a univalent negative ion.
They tend to go about this vigorously and as such undergo several chemical reactions because of that single electron they neeed.
ClBr, two nonmetals

To figure out how many atoms of copper you get in 1 gram of copper, you need to use copper's molar mass.
Answer:
D
Explanation:
The indivisibility of an atom was proved wrong an atom can be further subdivided into protons, neutrons and electrons. However an atom is the smallest particle that takes part in chemical reactions......
hope i helped
pls mark brainliest,,,,,thanks
