an atom contains 32 protons and has a mass number of approximately 72 amu what is the chemical symbol for the atom
2 answers:
<u>Answer:</u> The isotopic symbol of element is
<u>Explanation:</u>
Atomic number is defined as the number of protons that are present in an atom. It is represented as 'Z'
Z = Atomic number = Number of protons
Mass number of an element is defined as the sum of number of neutrons and number of protons that are present in an atom. It is represented as 'A'.
A = Mass number = Number of neutrons + Number of protons
The isotopic representation of an atom is:
where,
Z = Atomic number of the atom
A = Mass number of the atom
X = Symbol of the atom
We are given:
Number of protons = Atomic number = 32
Mass number = 72
The element having atomic number as 32 is germanium
Hence, the isotopic symbol of element is

When ammonia is reacted with HCl it abstracts proton from acid and forms Ammonium Ion and Chloride Ion.
NH₃ + HCl → ⁺NH₄ + Cl⁻ (simply Written NH₄Cl)
Structure,
The structure of Ammonium Chloride is among those structures which contains all three types of bonding's, i.e.
Ionic Bond
Covalent Bond
Coordinate Covalent Bond
Three Hydrogen atoms previously bonded with Nitrogen are covalent in nature. The new incoming proton from HCl forms co-ordinate covalent bond with Nitrogen and Chloride Ion containing negative charge make Ionic Bond with the positive Ammonium Ion. In question, if the line between Nitrogen and Chlorine atom is assumed covalent then it is incorrect. Structure is shown below,

Explanation:
This reaction is known as mercuric ion catalyzed hydration of alkynes.
The first step in the reaction is attack of the mercuric ion on the carbon-carbon triple bond, a bridged intermediate is formed. This bridged intermediate is attacked by water molecule to give an organomercury enol. This undergoes keto-enol tautomerism, proton transfer to the keto group yields an oxonium ion, loss of the mercuric ion now gives equilibrium keto and enol forms of the compound. The keto form is favoured over the enol form.
