The periodic table was organized by this property of elements.

What is atomic mass?

300

Atomic radius generally increases down a group due to what effect?

What is the addition of more shells?

300

This experiment led to the discovery of the nucleus.

What is the Gold Foil Experiment?

300

This subatomic particle determines the chemical behavior of an atom.

What is an electron?

300

2p6

400

Who is considered the father of the modern periodic table?

Who is Dmitri Mendeleev?

400

What happens to atomic radius across a period and why?

It decreases because more electrons are attracted to the higher nuclear charge

How many protons, neutrons, and electrons will be in the most abundant, neutral atom of Aluminum?

P: 13

[Xe]6s1

500

Why were gaps left in the periodic table?

What are future discovered elements?

500

Explain the trend in reactivity observed of Group 1 metals.

The reactivity increases because as there are more shells the atomic radius increases, which lowers the energy it requires to pull of the one valence electron (ionization energy)
