What is the purpose of superscript and subscript?

What is the purpose of superscript and subscript?

It hangs below its letter or number. It is used when writing chemical compounds. An example of subscript is N2. Superscript is the small letter / number above a particular letter / number.

What is the difference between superscript and subscript feature in MS Word?

A subscript or superscript is a character (number, letter or symbol) that is (respectively) set slightly below or above the normal line of type. It is usually smaller than the rest of the text. Subscripts appear at or below the baseline, while superscripts are above.

What is the function of superscript?

Superscripts are the little numbers written to the top right of numbers or variables. It means the exponent or power if written by itself with the number or variable. It can also mean the number of derivatives to take if written in between a function letter and its variable.

What is a superscript in math?

A small letter or number placed slightly higher than the normal text. Usually means how many times to use the value in a multiplication (also called an "exponent" or "power").

What does a subscript represent?

Subscripts are important numbers in formulas, especially when you're trying to understand how many atoms of an element are present. A subscript is a number to the right and below the abbreviation of an element that indicates the number of elements that are present.

What are the 5 examples of elements?

Pure Element Examples

  • Hydrogen (H) - nonmetal.
  • Helium (He) - nonmetal.
  • Oxygen (O) - nonmetal.
  • Neon (Ne) - nonmetal.
  • Nitrogen (N) - nonmetal.
  • Carbon (C) - reactive nonmetal.
  • Silicon (Si) - metalloid.
  • Magnesium (Mg) - alkaline earth metal.

How do you write the symbols of elements?

Each element is given its own chemical symbol, like H for hydrogen or O for oxygen. Chemical symbols are usually one or two letters long. Every chemical symbol starts with a capital letter, with the second letter written in lower case. For example, Mg is the correct symbol for magnesium, but mg, mG and MG are wrong.

Is n2o3 acidic or basic?

Dinitrogen trioxide (N2O3), nitrogen dioxide (NO2) and dinitrogen pentoxide (N2O5) are acidic.

What is the structure of n2o3?

Dinitrogen trioxide
Molecular shapeplanar, Cs
Dipole moment2.

What is the name for NI3?

Nitrogen triiodide

Why is NI3 explosive?

It is an extremely sensitive contact explosive: small quantities explode with a loud, sharp snap when touched even lightly, releasing a purple cloud of iodine vapor; it can even be detonated by alpha radiation....Nitrogen triiodide.

Why does NI3 not exist?

Answer. - F has very high electronegativity as compared to Cl & I. ... - Electronegativity difference between N & Cl/I is comparatively less and thus N-Cl or N-I bond is relatively weaker. - Less stable NCl3 or NI3 thus is explosive in nature.

Why is nitrogen triiodide explosive?

The reason nitrogen triiodide is so unstable is down to its molecular structure - one nitrogen atom and three iodine molecules all on one side due to how the nitrogen's electrons are arranged. ... And all that repelling causes something called bond strain, which makes the entire molecule extremely unstable.

Which is the formula for nitrogen Trihydride?


What is the most powerful eXplosive material?


How do you make nitrogen triiodide?

Crystals of iodine react with concentrated ammonia to precipitate nitrogen triiodide (NI3). The NI3 is then filtered out. When dry, the compound is so unstable that the slightest contact causes it to decompose into nitrogen gas and iodine vapor, producing a very loud “snap” and a cloud of purple iodine vapor.

Is nitrogen triiodide endothermic or exothermic?

2 NI3 (s) is endothermic. Endothermic compounds tend to be unstable.

What is the most sensitive explosive?

Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its "bang" from the 14 nitrogen atoms that compose it in a loosely bound state. This material is both highly reactive and highly explosive.

Is nitrogen triiodide ionic or covalent?

A chemical compound having chemical name as nitrogen triiodide. This compound is formed by the combination of nitrogen and iodine atoms. Both these elements are non-metals and thus form covalent compound. Hence, the given compound is a covalent compound.

Which formula correctly represents antimony trichloride?

Answer Expert Verified. Answer : The correct option is, Explanation : The symbol of antimony is 'Sb'.

What is the covalent name for H2O?

dihydrogen monoxide

Is H2O ionic or covalent?

H2O, more commonly known as water, is a covalent compound. This type of compound is the result of atoms, usually from nonmetal elements, sharing electrons. Water has a special type of covalent bond called a polar covalent bond.
