A particle that has the electron configuration 1s²2s²2p³ would: Have 2 filled orbitals and 3 partially filled orbitals.

Be able to bond with 2 hydrogens.

Have an electron configuration of a noble gas.

Have the electron configuration of an alkali earth metal.

Have 2 filled orbitals and 3 partially filled orbitals.

Explanation:

Hello there!

In this case, according to the given information of the electron configuration for that particle; it is possible for us to infer it has 5 valence electrons, as the electrons on its outermost shell (2). Moreover, we undertand this particle needs three bonds, does not have neither the electron configuration of a noble gas which ends by p⁶ nor that of an alkali earth metal as it ends by s².

Therefore, we infer the correct answer is Have 2 filled orbitals and 3 partially filled orbitals because according to the Hund's rule, the s orbital is fulfilled and the p orbital has 1 electron orbital fulfilled and two partially filled orbitals.

Regards!

i'm pretty sure its b i might be wrong though!

the answer would be b i believe
