Two models of the same compound are shown. on the left labeled model a 2 large overlapping black spheres with 3 small blue spheres overlapping the rear black sphere and 2 medium red spheres overlapping the front black sphere. one of the red spheres has a small blue sphere overlapping it. on the right labeled model b 2 c's connected by a black line. the c on the left has 3 h's attached by 1 black line each and the c on the right has 2 os attached to it. the top o is attached by 2 black lines and the bottom o by 1 black line. the bottom o also has an h attached to it by 1 black line. in what way is model a better than model b? model a shows the types of elements in the compound, but model b does not. model a shows the total number of atoms in the molecule, but model b does not. model a shows the three-dimensional shape of the molecule, but model b does not. model a shows the number of atoms of each element in the molecule, but model b does not.

Model A shows the three-dimensional shape of the molecule, but Model B does not.

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.
