Answer:
Will group 2 elements lose electrons to bond with nonmetals in group 17 in a
1:2 ratio?
Explanation:
Metals are electropositive in nature. This means that they loose electrons. Thus, metals form ionic bonds by loosing electrons to non metals.
Elements of group 2 have a valency of 2 while those of group 17 has a valency of 1 so the ratio in which group 2 elements bond with elements of group 17 is 1:2. Hence the answer.
Carbon and hydrogen and the number next to is the number of moles
Mirrors reflect light and lenses refract light.
Mirrors form images by reflecting all light that is incident on their surface, which allows us to see the reflections of objects in mirrors. Lenses, on the other hand, bend light and allow it to pass through them. The bending of light is used to form enlarged images, and for many other purposes as well.
