The configuration (σ2s)2(σ2s*)2(π2py)1(π2px)1 is the molecular orbital description for the ground state of

The answer is B2. The configuration has six electrons. B2 is the only answer choice that has six valence electrons. Boron is a chemical element with symbol B and atomic number 5. Shaped completely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, it is a low-abundance element.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
