H = hydrogen O = oxygen C = carbon N = nitrogen If you look at a Periodic Table of the elements, they're all on there.
What else can I help you with?
Using the rules for selecting symbols for the elements what could NOT be a correct symbol for a chemical element?
A correct symbol for a chemical element cannot contain two uppercase letters or start with a lowercase letter. For example, "Hn" or "eS" would not be correct symbols based on the rules.
Who invented symbols of elements?
The symbols of elements were created by various scientists over time based on the element's name, properties, or Latin name. One of the most well-known contributors to the modern periodic table and element symbols is Dmitri Mendeleev, who is credited with arranging the elements by their atomic mass and predicting the properties of undiscovered elements.
Why do some chemical symbols for elements consist of two letters and others only of one?
This is because there is not enough letters for all the elements if they were all with one letter and they would have to to repeat the letters again and you wouldn't know which element is which and if there was two letters it would be much much easier for you too know,so you could get the initial of the element.....:). ( it took me awhile to figure it out...) hope you understand it...
How could you recognize the chemical formula of an element?
The chemical formula of an element is typically represented by one or two letters. Each element has a unique symbol that is listed on the periodic table. For example, the symbol for hydrogen is H and for oxygen is O. By knowing the symbols and their corresponding elements, you can recognize the chemical formula of an element.
How do you spell alouminse?
Phonetically, this could be "elements" (parts, or chemical elements), or possibly "illuminance" (light).
Why can't you capitalize the second letter of a chemical symbol?
Capitalizing the second letter of chemical symbols would cause confusion. For example, if we capitalized the 'o' in Cobalt (Co) to appear as 'CO', then it would stand for two entirely different elements (carbon and oxygen).
Why is an element called an element?

What does oh mean on the periodic table?
On the periodic table, "Oh" is not an officially recognized chemical symbol. It could be confused with "O" for oxygen or "H" for hydrogen. However, "Oh" could refer to "ohm," a unit of electrical resistance, but it is not a chemical element. Always check the correct symbols for elements, which are typically one or two letters, with the first letter capitalized.
What symbols did John Dalton use for atoms?
John Dalton (1766-1844) was a science teacher who also kept detailed records of the weather. He suggested that every chemical element consisted of tiny particles, atoms, which were identical to each other but different from the atoms of other chemical elements. He also gave names and symbols to about 30 chemical elements. However, he thought that atoms were solid spheres, like metal balls, which could be never destroyed. Also, some substances which Dalton believed were elements are now known to be combinations of elements, or compounds.
What is the common chemical in a chemical reaction?
Oxygen as most reactions have it although it could also be hydrogen
Why are elements given a symbol?
Different languages have their own words for elements, but chemical symbols are international, so they provide a universal way of specifying chemicals. A chemical formula is not specific to any language and will make the same sense in any country. Also, many molecules and formulae involve a large number of different elements, or complex arrangements of the same elements, and symbols provide a way to express them without being too long.
Why do scientists use chemical symbols rather than words to represent a compound or element?
The symbols (formulas) show the elements or ions in a compound. Sometimes it is easier to see the relationships between the elements with an empirical formula. But with larger molecules with atoms in complex arrangements, the written names are sometimes more appropriate. (e.g. sodium benzoate NaC7H5O2 which is formed from an ion of benzene C6H6)
