How many electrons are in the outermost energy level of a chloride ion (cl–) in table salt

8

Explanation:

We see that it has 7 electrons in its outermost energy level. It needs only one more electron to give it an octet of electrons and a noble gas configuration. Hence, a chloride ion has 8 electrons in its outermost energy level.

thermophiles, notice the prefix thermo.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
