What does the peak of a probability curve for an electron in an atom indicate?

The options for the given question are given below.

a) the location where there is zero probability of finding the electron

b) that the electron’s location can be precisely determined

c) that Heisenberg’s uncertainty principle is violated

d) the distance from the nucleus at which the electron is most likely to be found

Answer : The correct option is d "the distance from the nucleus at which the electron is most likely to be found"

Explanation :

The probability distribution curve is the plot of density function ( represented by y axis) vs the distance of electron from the nucleus ( represented by x axis).

The peak of the curve shows the maximum density of finding an electron. The corresponding value on x axis therefore represents the distance at which this maximum density can be located.

Therefore we can say that the peak of a probability curve for an electron in an atom indicate the distance from the nucleus at which the electron is most likely to be found.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
