1. What are the biotic (living) factors? 2. What are the abiotic (nonliving) factors?
3. Zoom-in and click on each of the biotic factors. Know what they look like. Then hit run. What do you notice? Identify predators and prey.
4. Click on each of the biotic factors. You will see a list of traits that you can change. State the traits that can be changed for each of the biotic factors.
5. The bar graph that you see is called a histogram. Examine one histogram. Describe what it is showing.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
