Answer:

B

Explanation:

It is a quantitative observation because <u>quantitative</u> data deals with values and numbers like height, weight, body temperature, etc.

The question also states that the biologist determines that the body temperature is 29⁰C, this is classified as an observation.

Hence, the answer is B, because the data is quantitative (as it contains numerical values), and the biologist observed this, most likely through a series of test.

1. Write the complete electron configuration for each atom on the blank line. Lithium Fluorine Carbon Argon Sulfur Nickel Rubidi
suter [353]

Answer:

Explanation:

Answer 1:

Lithium : 1s2 2s1  Fluorine: 1s2 2s2 2p5   Carbon: 1s2 2s2 2p2

Argon : 1s2 2s2 2p6 3s2 3p6   Sulphur: 1s2 2s2 2p6 3s2 3p4

Nickel: 1s2 2s2 2p6 3s2 3p6 3d8 4s2  Rubidium: 1s2 2s2 2p6 3s2 3p6 3d10  4s2 4p6 5s1   Xenon: 1s2 2s2 2p6 3s2 3p6 3d10  4s2 4p6 4d10 5s2 5p6

 

Answer 2:  A. Fluorine B. Calcium  

C. It is Tellurium if this was the exact electronic configuration 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p4 you intend to write, if not, no element has such electonic configuration.

D. Bromine but the correct electronic configuration is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p5

When atoms gain electrons, they can become larger, because the addition of an electron increases electrostatic repulsion.
astra-53 [7]

Answer:True

Explanation: An anion has a larger radius than a neutral atom because it gains valence electrons. There are added electron/electron repulsions in the valence shell that expand the size of the electron cloud, which results in a larger radius for the anion.

hit the crown for me pls :)

Have a great day
