forgive me if im incorrect or leaving things out
The answer would be A) The plum pudding model.
Answer:
Since they have an electronegativity difference of 0.4 then they will form a Covalent Bond.
I think it’s most likely a, but it could be D :)
Answer:
First ionization of lithium:
.
Second ionization of lithium:
.
Explanation:
The ionization energy of an element is the energy required to remove the outermost electron from an atom or ion of the element in gaseous state. (Refer to your textbook for a more precise definition.) Some features of the equation:
- Start with a gaseous atom (for the first ionization energy only) or a gaseous ion. Write the gaseous state symbol next to any atom or ion in the equation.
- The product shall contain one gaseous ion and one electron. The charge on the ion shall be the same as the order of the ionization energy. For the second ionization energy, the ion shall carry a charge of +2.
- Charge shall balance on the two sides of the equation.
First Ionization Energy of Li:
- The products shall contain a gaseous ion with charge +1 as well as an electron .
- Charge shall balance on the two sides. There's no net charge on the product side. Neither shall there be a charge on the reactant side. The only reactant shall be a lithium atom which is both gaseous and neutral: .
- Hence the equation: .
Second Ionization Energy of Li:
- The product shall contain a gaseous ion with charge +2: as well as an electron .
- Charge shall balance on the two sides. What's the net charge on the product side? That shall also be the charge on the reactant side. What will be the reactant?
- The equation for this process is .
