Quiz 13

The half-life of an element is the time it takes for 1/2 of any quantity of that element to decay into another element

Elements decay into other elements through delta, epsilon, and zeta radiation

Francium has a half life of 22 minutes, so 8 grams of Francium will decay into 2 grams in 44 minutes.

Francium has a half life of 22 minutes, so 2 grams of Francium will decay into 0 grams in 88 minutes.

Alkali Metals are harder than other metals

Alkali Metals conduct heat and electricity well

Alkali metals have the same number of protons after donating their outer electron

Alkali metals have the same chemical properties after donating their outer electron

Alkali metals play an important role in creating action potentials in our nerves and muscle contractions

Over 30% of all of the energy our bodies use are spent pumping Alkali Metal ions across our cell membanes

Alkali Earth metals are also required to pump alkali metals across membranes and facilitate muscle contraction

Concentration gradients are when there is more of an element in each Liter of fluid on one side of a membrane than the other

Since we do not have electrical wiring in our bodies, we cannot have voltage between different parts of our body
