Write a chemical equation representing the first ionization energy for lithium while using e as a symbol for electron.

The reason is because IEs are usually reported from the neutral atom, that is, IE2 is the energy required to remove two electrons from a neutral Li atom, as above, rather than the additional energy required to remove one more electron from an Li+ cation.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.
