Which is not a typical step when performing scientific research?
a. testing hypotheses
b. conducting experiments
c. establishing laws
d. making observations

Option C

Explanation:

When conducting research, scientists use the scientific method to collect measurable, empirical evidence in an experiment related to a hypothesis (often in the form of an if/then statement), the results aiming to support or contradict a theory.

The steps of the scientific method go something like this:

1. Make an observation or observations.

2. Ask questions about the observations and gather information.

3. Form a hypothesis — a tentative description of what's been observed, and make predictions based on that hypothesis.

4. Test the hypothesis and predictions in an experiment that can be reproduced.

5. Analyze the data and draw conclusions; accept or reject the hypothesis or modify the hypothesis if necessary.

6. Reproduce the experiment until there are no discrepancies between observations and theory.

explanation:

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.
