Shorthand notations are a part of the Wolfram Language's rich syntax system that allows multiple ways to feed arguments to functions. In addition to creating compact code, using shorthand notation lets you customize your workflow in the Wolfram Language.
<h3>What is the shorthand notation of an atom?</h3>
Often, a shorthand method is used that lists only those electrons in excess of the noble gas configuration immediately preceding the atom in the periodic table. For example, sodium has one 3s electron in excess of the noble gas neon (chemical symbol Ne, atomic number 10), and so its shorthand notation is [Ne]3s1.
<h3>How do you write shorthand configuration?</h3>
In shorthand electron configuration, the electron configuration starts with the symbol of the noble gas in the previous period, followed by the additional configuration of the electrons for the given element. For example, aluminum has the atomic number 13, which is the number of protons in the nuclei of its atoms.

Answer:
126 g of H₂O
Explanation:
Firstly, we complete the equation:
2H₂ + O₂ → 2H₂O
If we have 7 moles of hydrogen, we assume, the oxygen is in excess.
Ratio is 2:2.
2 moles of hydrogen can produce 2 moles of water
Then, 7 moles of H₂ must produce 7 moles of water.
We convert moles to mass → 7 mol . 18 g/mol = 126 g
It is a less reactive metal then sodium and magnesium
Answer: The correct answer is Option a and d.
Explanation: Both the salts are ionic in nature because when dissolved in water, they dissociate into their respective ions.
Ionic compounds are held together by ionic bond. They are neutral compounds as both positive and negative charges neutralize each other. These compounds are also good conductors of electricity because of the presence of ions.
As both the salts have different molecular formula, both of them will have different crystal lattice system and hence, different crystal lattice energy.
From the above information, the correct options are option a and option d.
The name for NH3 is Nitrogen trihydride.
