Answer:

20 neutrons

Explanation:

This will get you the mass number of the most abundant potassium isotope. You now know that the most abundant isotope of potassium contains 20 neutrons. All isotopes of potassium will have the same number of protons inside their nucleus, i.e. 19 protons.

I hope this helps you.

Resonance structures have _______ connectivity of atoms and _______ distribution of electrons.

Arte-miy333 [17]

Answer:

Resonance structures have same connectivity of atoms and differ only in distribution of electrons.

Explanation:

Atoms supply the electrons from their outer electron shells. Electrons are found free in nature and are grouped around the nucleus into shells. Electrons can be further explained as negatively charged subatomic particle. Electrons have properties of both particles and waves and they can be moved around.

Resonance structures are imaginary structures and not all of them are created equally. Resonance structures have two or more possible electron structures, and, the resonance structures for a particular substance sometimes have different energy and stability. When resonance structures are identical, they are important descriptions of the molecule. The position of the atoms is the same in the various resonance structures of a compound, but the electrons are distributed differently around the structure.

Let this oscillator have the same energy as a mass on a spring, with the same k and m, released from rest at a displacement of 5

allochka39001 [22]

There are a lot of same examples that you may have worked before, where the mass on a spring uses a classics when it comes to mechanics. So in this system, always put in your mind that there is an enormous quantum standard that one can use in the equation. It should be 2.10x10 raise to a negative sixth. J.

Find the magnitude of the gravitational force a 63.5 kg person would experience while standing on the surface of Earth with a ma

Anastaziya [24]

Answer: 3976N

Explanation:

Using the formula for calculating gravitational force between two masses, we have

F = GMm/r^2

Where G is the gravitational constant

M and m are the masses

r is the distance between the masses

F= 6.673 × 10-¹¹ × 5.98 × 10²⁴ × 63.5/ (6.37 × 10^6)^2
