Among ¹⁴⁰₅₅Cs and ¹³³₅₅Cs, <u>¹³³₅₅Cs</u> is more stable.
<h3>Briefly explained</h3>
Let's review the criteria that are used to determine a stable isotope. A stable isotope will have more neutrons than protons with a neutron to proton ratio somewhere between one and 1.52 On the high atomic number, we're up to 152 at low atomic numbers were closer to one. More stable isotopes have an even number of protons. And neutrons.
And stable isotopes have their proton or neutron number equal to one of these magic numbers. So if we have season one, It has 85 Protons are start 85 neutrons And 55 protons. So we have a neutron to proton ratio of 155 for CCM 1 33. We have 78 neutrons and 55 protons for a neutron to proton ratio of 1.42. 155 is a little high for z equal to 55.
Both of these are also odd. So ¹⁴⁰₅₅Cs is the least stable. ¹³³₅₅Cs is the most stable.

The experimental value of Avogadro's number will be ±0.050.
<h3>What is the degree of accuracy?</h3>
The degree of accuracy refers to the extent to which a measurement is correct. Now we know that the measurement obtained by an instrument is as correct as its degree of accuracy.
Hence, given that the margin of error is about 0.050, the experimental value of Avogadro's number will be ±0.050.

Glucose and galactose (both simple sugars) are produced from the hydrolysis of lactose.
Answer:
In chemistry and physics, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a
