Answer:
electron sea model for metals suggest that valence electrons drift freely around the metal cations.
Explanation:
Explanation: In electron sea model, the valence electrons in metals are delocalized instead of orbiting around the nucleus. ... These electrons are free to move within the metal atoms. Thus, we can conclude that the electron sea model for metals suggest that valence electrons drift freely around the metal cations.

Answer:
A) ψ² describes the probability of finding an electron in space.
Explanation:
The Austrian physicist Erwin Schrödinger formulated an equation that describes the behavior and energies of submicroscopic particles in general.
The Schrödinger equation i<u>ncorporates both particle behavior</u>, in terms of <u>mass m</u>, and wave behavior, in terms of a <u><em>wave function ψ</em></u>, which depends on the location in space of the system (such as an electron in an atom).
The probability of finding the electron in a certain region in space is proportional to the square of the wave function, ψ². According to wave theory, the intensity of light is proportional to the square of the amplitude of the wave, or ψ². <u>The most likely place to find a photon is</u> where the intensity is greatest, that is, <u>where the value of ψ² is greatest</u>. A similar argument associates ψ² with the likelihood of finding an electron in regions surrounding the nucleus.
Answer: m-%(Ca) = 40.08 / 110.98
Explanation: molar mass of CaCl2 is 40.08+ 2·35.45 = 110.98
Think you have one mole substance. It contains 40.08 g Ca
