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°

The answer is Sulfuric acid
Answer:
The answer to your question is 2.3 g
Explanation:
Data
Molecule = NaOH
grams of Na in 4 g of NaOH
Process
1.- Calculate the molecular mass of NaOH
molecular mass = (1 x 23) + (1 x 16) + (1 x 1)
= 23 + 16 + 1
= 40 g
2.- Calculate the atomic mass of sodium
atomic mass = 23 g
3.- Use proportions to solve this problem
40 g of NaOH ---------------- 4 g of NaOH
23 g of Na ---------------- x
x = (4 x 23) / 40
x = 2.3 g
