Consider the group 1A elements sodium (period 3), potassium (period 4), and rubidium (period 5). What would you predict about th
enyata [817]

The correct answer is Na > K > Rb.  

The order predicted would be ionization energy of sodium is greater than the ionization energy of potassium, which is greater than the ionization energy of rubidium.  

The ionization energy refers to energy, which has to be supplemented to a gaseous atom in order to withdraw an electron and produce a positive ion. The ionization energy decreases in going down a group. The cause of the decline of the ionization energy down a group is that as one moves down a group, the size of the atom increases that signifies that the valence electrons get further away from the nucleus, and thus, less energy is required to withdraw the electrons.

2. Write the chemical equation for the reaction NaOH Sodium Hydroxide AgNO3 Silver Nitrate
lys-0071 [83]

Answer:

AgNO3 + NaOH = AgOH + NaNO3.

Explanation:

<em><u>Balancing Strategies: In this reaction, the products are initially NaNO3 + AgOH. However the AgOH would break down into Ag2O and H2O. This would give us NaNO3 + Ag2O + H2O as our products for the overall reaction.</u></em>
