How is the reactivity of metals related to the periodic table?

Answer 1

In the alkali metals column (Group 1), atomic radius increases down the group and reactivity increases. There are more shells preventing the attraction between the positive nucleus and negatively charged outer electron. (All Group 1 elements have 1 electron in their outer shell). Also, because they contain more shells down the group, the distance between the nucleus and electrons is increased. Therefore the electrostatic force is lessened between them. Both of these allow the outer electron to be lost easier to other elements, thus increasing reactivity.

Answer 2

At least for the Alkali and Alkaline Earth metals, the higher the ionization energy, the less the reactivity.

This is because when a metal reacts, it loses electrons to form ions with stable electron configurations.

When a lot of energy is required for it to lose electrons, it is going to be less likely to react than a metal that easily sheds electrons.

Therefore, the lower the ionization energy, the more reactive a metal will be.

Answer 3

At least for the Alkali and Alkaline Earth metals, the higher the ionization energy, the less the reactivity.

This is because when a metal reacts, it loses electrons to form ions with stable electron configurations.

When a lot of energy is required for it to lose electrons, it is going to be less likely to react than a metal that easily sheds electrons.

Therefore, the lower the ionization energy, the more reactive a metal will be.

Answer 4

The reactivity of metals is related to their position on the Periodic Table. As you move down a group from top to bottom, reactivity generally increases because outer electrons are further from the nucleus. Among the transition metals, reactivity can vary depending on the number of valence electrons and electronic structure.

Answer 5

what can you deduce about the relationship between electron affinity and reactivity of non-metals

Answer 6

For metals in the same group, the higher the atomic number the higher the reactivity. This trend is seen as one moves down a metal group.

Answer 7

Group 1 elements have larger atomic radius and greater reactivity than that of the adjacent group 2 elements.

Answer 8

When the atomic radius decrease the ability to loss electrons decrease.

Answer 9

Reactivity of metals describe the order of sequence of metals depending on reactivity. Potassium is at the top of reactivity series.
