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.

Answer:

You should follow these steps:

Count each type of atom in reactants and products.

Place coefficients, as needed, in front of the symbols or formulas to increase the number of atoms or molecules of the substances.

Repeat steps 1 and 2 until the equation is balanced.

An explanation of what will happen every time in a specific situation

kramer

The one that is being described above is what we call SCIENTIFIC LAW. Scientific law is what explains of what will happen every time in a certain situation. This is also different from scientific theory since scientific theory only gives an explanation to a group of happenings and this can still be modified. Hope this helps.

Which periodic trend quantifies the amount of energy required to remove an electron from a neutral, gaseous atom?.

igor_vitrenko [27]

Ionization energy refers to the amount of energy needed to remove an electron from an atom. Ionization energy decreases as we go down a group. Ionization energy increases from left to right across the periodic table.

<h3>What is ionization energy?</h3>

Ionization is the process by which ions are formed by the gain or loss of an electron from an atom or molecule.

Ionization energy is defined as the energy required to remove the most loosely bound electron from a neutral gaseous atom.

When we move across a period from left to right then there occurs a decrease in atomic size of the atoms. Therefore, ionization energy increases along a period but decreases along a group.

Smaller is the size of an atom more will be the force of attraction between its protons and electrons. Hence, more amount of energy is required to remove an electron.

Thus, we can conclude that the energy required to remove an electron from a gaseous atom is called ionization energy.

How many moles are in 22 grams of argon

Strike441 [17]

<span>number of moles are the amount of substance of an element .
number of moles can be calculated as follows;
number of moles = mass present / molar mass of element
molar mass of Ar - 40 g/mol
number of moles of Ar = 22 g / 40 g/mol = 0.55 mol .
there are 0.55 mol of Ar</span>

What are the three challenges of a cell?

Zolol [24]

<span>The cell must exchange materials with the environment across the surface membrane. An increase in size will result in a relatively greater increase in volume and mass than in surface area, so that the cell will lose effective exchange capacity.
