Use the electron configurations and the periodic table to answer the questions:
HEILL
1s
2p
Which element is this?
fluorine (F)
carbon (C)
nitrogen (N)
oxygen (0)

The given electronic configuration indicates Fluorine (F).

Explanation:

The electronic configuration of each and every element in the periodic table reflects its character, stability and their chemical as well as physical properties. It is given that 1s 2p that means 1s, 2s orbitals are filled  and then 2p orbitals are maximum filled, then it contains 9 electrons, that is 2 electrons in 1s orbital, then 2 electrons in 2s orbital then 5 electrons in the 2p orbital. So 1s² 2s² 2p⁵ is the electronic configuration indicates the element fluorine (F).

The answer is b because c don't explain why the moths are on them and it isn't a because as we know only one species of moth does this
