Question

Examining a Trend in the Periodic Table of Elements
Objective:
This topic examines the trend of reactivity in the alkaline earth metals as you go down the second column of the periodic table of elements.
Research Questions:
What do you think will happen as you go down the column of alkaline earth metals?
What do you think would happen if you went to the first column of the periodic table?
Do you notice a trend that could apply to the whole periodic table?

Answer 1

Answer:

Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element's properties.

Explanation:

Hope it helps

Answer 2

Answer:

As we go down the column of alkaline earth metals (group 2), we see that the metals get bulkier, their ionization potential decreases, melting and boiling points decrease, electron affinity and electronegativity decrease, nuclear charge decreases, and metallic character increases
