Pls answer. will give thanks ! 1. Potassium (K) is in row 2 of the periodic table. how many energy shells does one atom of Potassium have?

2. Carbon (C) is in column 14 of the periodic table. how many electrons are in the outermost energy shell of an atom of carbon?

3. Nickel (NI) has an atomic number of 28. how many protons are in the nucleus of one atom of nickel?

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.
