400

The family in which magnesium belongs to 

Alkaline Earth Metals

400

The metalloid in group 13

B (Boron)

400

Group of silvery metals that react with water

Alkali Metals

400

Which alkaline earth metal is the most reactive?

Radium

400

Rubidium has a lower ionization energy than sodium. One reason for this is that the —

valence electrons are farther from the nucleus

500

The center block of the periodic table (3-12) make up which group of elements?

Transition Metals

500

The least electronegative element

Francium
500

Metals are electron donors, making positively charged ions called...

cations

500

J. Priestly discovered that many carbon-containing materials burn in the presence of oxygen gas. However, the rest of the elements in the carbon family do not react the same way.

What explains this phenomenon?

Reactivity decreases going down a family.

500

Why the ionization energy greater with lithium than it is with francium 

The effective nuclear charge is lesser on francium's valence electrons, allowing electrons to be removed with less energy compared to lithium.
