Polonium is a rare element with 33 radioisotopes. The most common one, 210Po, has 84 protons and 126 neutrons. When 210Po decays
Fofino [41]

Answer:

Lead Pb

Explanation:

Firstly, we need to know what occurs when a radioisotope emits an alpha particle. An alpha particle is an helium atom. When an isotope emits an alpha particle, it loses an helium atom corresponding to subtracting 4 from its mass number and 2 from its atomic number. This of course coupled with the release of radiation.

Now, we polonium has a proton number of 84 and a mass number of 210. Subtracting 2 and 4 respectively from its proton and mass numbers will yield 82 and 206 proton and mass numbers respectively.

Hence, the decomposition of the Po-210 isotope will yield an element with 82 proton number and 206 mass number. This corresponds to the element Lead.

210Po ——> 206Pb + alpha particle + radiation

Define the terms "Aldonic Acid", "uronic Acid", and "Aldaric Acid"
sesenic [268]

Explanation:

Aldonic Acid:

Aldonic acids are suger acids.

General formula of aldonic acid = HOOC-(CHOH)_n-CH_2OH

Aldonic acids are obtained by the oxidation of aldehydic group of suger.

So, aldonic acids have hydroxyl group at one terminal and carboxylic group at another terminal.

Gluconic acid is an example of aldonic acid.

Uronic Acid:

It is also a type of suger acid having carbonyl functional group at one terminal and carboxylic group at other terminal.

It is obtained by oxidation of hydroxyl group of the sugar.

Aldaric Acid:

Aldaric acid is also a type of sugar acid having carboxylic acid functional group at both the ends.

Both the hydroxyl group and aldehydic group are oxidized to form class of compound, called aldaric acid.
