Answer:
K
Explanation:
Ionization energy refers to the energy required to remove an electron from an atom. It usually increases across the period due to the increase in the size of the nuclear charge and decreases down the group due to increase in the number of shells.
If we look at the element, K, it has only one electron in its outermost shell. This implies that after this one electron is removed, the second ionization energy involves the removal of an electron from a filled shell.
This usually requires a lot of energy. Hence, the element having the highest difference in energy between first and second ionization energy is K.
Because the exponent in the 10s term is positive move the decimal point 4 places to the right:
1.2 ×104 =12,000
Convection is the transfer of heat/thermal enrgy by the movement of a fluid(either a liquid or gas).

<h3>Further explanation</h3>
Carbon-14 is a radioactive isotope that can decay. This isotope can be used to determine how long ago an organism died by knowing the ratio from 12C to 14C
Can be formulated
Or we can use :
The half-life of C-14, 5730 years, so the decay constant :
Assume the initial C-14 activity was 13.6 disintegrations/min/g of C
Due to its small size, lithium has a high melting and boiling point.
<h3>
Why does lithium have high melting and boiling point explain?</h3>
With only one valence electron to contribute to the metallic lattice, lithium and potassium are both alkali metals. We could infer that the metallic bonding is less strong between the electron cloud and the larger potassium cation than it is in the lithium structure. This means that because lithium creates a smaller cation, the electrostatic force in this situation should be greater also Lithium has high ionization energy and a high melting and boiling point because of its small size. As a result, its crystal structure has an extremely high binding energy.
<h3>
Alkali metals</h3>
The chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium make up the alkali metals (Fr). They make up group 1, which is located in the s-block of the periodic table, along with hydrogen.
