Help! 100+ pointss To demonstrate the arrangement of atoms in liquids, a teacher tapes off a circular section on the classroom floor. How should the students modeling as atoms of liquids stand or move in the taped-off section?
Question 2 options:

Leave half the space in the circle vacant and move around holding hands

Move into the circle, a few at a time, and run randomly over the entire section

Run quickly, a few at a time, and pretend to bump off the boundary of the circle

Crowd very close together so that there is no space inside the section to move

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.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

here are some of the ways in which chemical and nuclear reactions differ.
