Answer: Option (a) is the correct answer.

Explanation:

Precipitation is defined as the formation of a solid in a liquid which is not soluble.

Therefore, presence of an insoluble solid substance does not affect soil formation.

Whereas when natural forces like wind, water etc which erode away rocks and soil are known as erosion. Also, time is a factor that also affects the soil formation.

For example, in rainy season due to heavy rain soil erosion occurs which affects the soil formation.

<h3>What are elements?</h3>

Elements are pure substances which are composed of similar atoms.

Elements are defined as substances which cannot be split into simpler substances by an ordinary chemical process.

Elements have different physical and chemical properties and can be classified into:

metals
semi-metals
non-metals

In conclusion, the physical and chemical properties of the elements vary from metals to non-metals.

What’s the distance from the nucleus of an atom to its theoretical outer edge of electron orbits

ollegr [7]

Answer:

The range of atoms = (30-300 pm) depending upon the element

Explanation:

The Atomic radii of the atom is the distance from the center of the circle to the outermost orbital.

The center of the circle is the nucleus and the radii is the outermost boundary.

The actual size of the atom is decided on the basis of the Zeff . Also known as effective nuclear charge.

Zeff: It is the net positive charge felt by the outermost electron by the nucleus.

The value of Zeff depends upon the shielding constant. More the shielding less will be the Zeff . Hence the size of the atom increases.

Due to shielding the outermost electrons feel less pull of nucleus.

The greater the Zeff , the smaller the radius of the atom.

The formula used to calculate the atomic mass is :

$r_{n}=\frac{52.9n^{2}}{Z}$ pm

Here "pm"= picometers

$1 pm = 10^{-12}m$

The size of the smallest atom H-atom = 120 pm

The range of atoms = (30-300 pm)
