Why doesn't the outer electron on the potassium atom experience the full charge of the protons in the nucleus (+19)?

Chemistry

Answer:

There are 18 electrons shielding it from the nucleus

Explanation:

The shielding effect is the reduction in the effective nuclear charge on an electron, due to repulsion by the inner electrons in the atom.

Potassium has 19 electrons, 18 of which are in the inner shells of the atom. These 18 electrons "shield" the outermost electron from feeling the effect of the nuclear charge. The magnitude of effective nuclear charge felt by an electron as a result of screening by other inner electrons is given by Slater's rules.

What happens when sodium and cholorine are mixed
tigry1 [53]

Answer:

The short of it is you would create salt.

Explanation:

If sodium metal and chlorine gas mix under the right conditions, they will form salt. The sodium loses an electron, and the chlorine gains that electron. This reaction is highly favorable because of the electrostatic attraction between the particles. In the process, a great amount of light and heat is released.

Orlov [11]

The best description of the process to draw the segment is B. b place a compass at one endpoint of the segment and trace an arc. do the same from the other endpoint. draw a line through the intersections of the arcs.

<h3>What is a segment bisector?</h3>

It should be noted that a segment bisector simply means a line to segment which cuts another line segment at the center but dividing the lines into two equal halves.

In this case, based on the information given, the best description of the process to draw the segment is to place a compass at one endpoint of the segment and trace an arc, do the same from the other endpoint. draw a line through the intersections of the arcs.

In conclusion, the correct option is B.
