What is a major disadvantage of using solar power? (4 points)
damage to wildlife
radioactive waste
electricity cannot be generated
requires large storage batteries

electricity cannot be generated

Explanation:

A solar energy is a renewable source of energy in which the light energy from sun is used to heat up the solar device which converts the heat energy into electrical energy.

The major disadvantage of this technology is that the electricity cannot be generated in cloudy and rainy weather. Also in night no electricity will be generated as the device works in the presence of sunlight.

gravity causes stares to cluster i think so

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
