Answer:

It was the last element first discovered in nature, rather than by synthesis. Outside the laboratory, francium is extremely rare, with trace amounts found in uranium and thorium ores, where the isotope francium-223 continually forms and decays

What element has a total of 3 p-sublevel electrons?

den301095 [7]

Elements with three p-electrons....

That would be N, P, As, Sb, and Bi -- elements in group 15

For example, energy diagram showing "empty" orbitals up through the 3p.

3s __

.....2p __ __ __

2s __

1s __

Energy diagram of phosphorous showing three unpaired electrons in 3p-sublevel

.....3p ↑_ ↑_ ↑_

3s ↑↓

.....2p ↑↓ ↑↓ ↑↓

2s ↑↓

1s ↑↓

According to Hund's rule, the electrons singly occupy the p-orbitals, and all have the same spin.

How can you estimate the pH range of an indicator’s color change? Why do some indicators have two separate pH ranges?

erastova [34]

The color change of a pH indicator is caused by the dissociation of the H+ ion from the indicator.

<h3 /><h3>What is indicator?</h3>

In science, a marker capability or a trademark capability of a subset An of a set X is a capability characterized from X to the two components set {0, 1}, normally signified as, and it demonstrates whether a component in X has a place with A. Markers are insights used to gauge current circumstances as well as to figure monetary or financial patterns. In the realm of money management, pointers regularly allude to specialized diagram designs getting from the value, volume, or open revenue of a given security.
