THE RADIUS OF THE TENTH ORBIT IN A HYDROGEN ATOM IS 52.9A°
<h3>How does an electron orbit work? </h3>
The three-dimensional area covering the nucleus of an atom is called electron orbital. Electrons sometimes fill low-energy orbitals which are closer to the nucleus before filling the higher ones. They mostly fill the orbitals as singly as they can and that filling is known as Hund’s rule. In the wave-like property, electrons don’t orbit a nucleus in the way a planet orbits the sun but however, but they exist as standing waves. The lowest energy possible an electron can take is the same as the fundamental frequency of a wave on a string.
the radius of the first orbit =0.0529nm
radius ∝ n²/z
radius of 10th orbit =(0.0529×100)nm=52.9A°

Answer:
The correct option is;
C. Two in the first energy level, six in the second energy level
Explanation:
The electrons in an atom are arrange in orbital shells which are situated at different levels within the structure of the, depending on the energy of the electron. Electrons with the least amount of energy are found in the shell closest to the nucleus of the atom which is the first energy level
The maximum number of electrons that can be found in a given an energy level is obtained with the following formula;
The number of electron = 2 × n²
Where;
n = The number of the different energy level
Therefore;
The maximum number of electrons in the first energy where n = 1 is given as follows;
The number of electron = 2 × 1² = 2 electrons
The maximum number of electrons in the second energy level where n = 2 is given as follows;
The number of electron = 2 × 2² = 8 electrons
Given that there are only 8 electrons in the atom, we therefore have, 2 electrons in the first energy level and the remaining 8 - 2 = 6 electrons in the second energy level.
A compound is formed due to the chemical combination or chemical reaction between two or more elements. The elements forming a compound cannot be separated by physical means. The properties of the compound is different from the properties of the elements forming it.
Based on this, the answer would be:
They are different.
