Question

A) In terms of its electronic configuration, explain why calcium adopts a charge of +2 when it ionizes.

B)Which of the following forms of electromagnetic radiation has the highest frequency? infrared (IR), x-ray, radio waves, microwave, or ultraviolet (UV)

C) Which of the following molecules has the weakest bond between the two atoms? F2, CO, O2, N2

D)Which of the following is not true according to modern quantum mechanics?

-the electron orbits the nucleus at certain allowed orbital radii

-orbitals are used to describe behavior of electrons

-the exact location of the electron cannot be pinpointed at all times

-emission of light can result when an electron jumps between two energy levels

Explanation / Answer

A) Calcium adopt charge ca+2 during because it release lots of energy compare to ca+ and due to highly exothermic it is most stable.

B) X-ray [highest frequency after gamma ray]

c) CO [ polar charge presence]

D) -the exact location of the electron cannot be pinpointed at all times

[by probability finding we can find exact loction]
