The answer should be A, the number of electrons increases by 1, from left to right.
Across the periods (horizontal direction) in periodic table, each element has one more electron then the one before it. The number of period determines the number of occupied electron shells of the elements in that period. Which means, period 1 elements have 1 occupied electron shell, period 2 has 2, period 3 has 3 etc.
Therefore, the answer is A, we always go from left to right, and plus since period 2 elements only have 2 occupied electrons so their 2nd electron shell electrons must increase throughout the period.

Ionic substances produce ions in solution while molecular substances produce molecules in solution.
<h3>What is a solution?</h3>
A solution is a combination of solute and solvent. The species that occur in solution depends on the type of substance that was dissolved. Since the table is not shown, we do not know exactly what compounds were dissolved in solution.
Generally, if an ionic substance is dissolved in solutions that ions are present in the solution. If a molecular substance is dissolved in solution, molecules are present in solution.

Answer:
A metallic bond is the sharing of many detached electrons between many positive ions, where the electrons act as a "glue" giving the substance a definite structure. It is unlike covalent or ionic bonding. Metals have low ionization energy. Therefore, the valence electrons can be delocalized throughout the metals.
