What do the symbol represent in a chemical formula 0 atoms 1 atoms 2 atoms or the need for subscript?
The symbols in a chemical formula represent the elements present in the compound. A zero atom, or no atom, is denoted by omitting the element symbol from the formula. A subscript of 1 is not usually written in a chemical formula as it is implied. If there are more than one atom of an element, the number of atoms is indicated by a subscript after the element symbol.
What does chemical formula of a compound represents?
A chemical formula or molecular formula is a way of expressing information about the atoms that constitute a chemical compound.So this being said, that basically means the chemical formula represents the atoms that are bonded to one another (An atom is classified according to chemical element and isotope more specifically)
Do the subscripts in a chemical formula represent the relative mass of each atom in a chemical compound?
It usually represent the amount of atoms in a molecule, i.e. Na2CO3 + 2HCl --> 2NaCl + CO2 +H2O So, in the first compound, there are 2 sodium atoms, one carbon atom and 3 oxygen atoms. In water, there is one hydrogen atom and 2 oxygen atoms..
A binary compound with a more positive or basic element or radical?
In a binary compound, the element that is more positive or basic is typically listed first in the chemical formula. This element is usually a metal or a positively charged ion, while the element listed second is often a nonmetal or a negatively charged ion. The more positive element is usually the one that forms cations in chemical reactions.
How is the chemical formula for hydrogen found?
Hydrogen is an element, with the symbol of H. Hydrogen gas is usually found as a diatomic molecule- 2 atoms of hydrogen linked to each other, having a formula of H2
In a chemical formulas the number of a Atoms for each element is usually indicated by a?
its usually indicated by a subscript! :D
What is the chemical formula for native selenium?
The chemical formula for element selenium is indicated by se. Native selenium is a rare mineral which does not usually forms good crystals. Hence it is used in the manufacture of specimens

Why does oxygen not have a subscript?
Oxygen does not have a subscript since it is an element. Subscripts are usually found in the chemical formula of a compound and not an element.
In the chemical formula of a binary ionic compound the last part is?
The last part in the chemical formula of a binary ionic compound is usually the anion, which is negatively charged and is represented by its element symbol. It is written after the cation in the formula to show the complete chemical composition of the compound.
Is copper an compound or element?
Copper is a chemical element. It can be a compound but copper is usually known as a chemical element.
Is oxidation number shown with a subscript?
No: An oxidation number, if shown at all in a chemical formula, is shown with a superscript. The oxidation number is usually shown only for monatomic ions.

What is the symbol of the chemical element scandium?
The symbol if the chemical element Scandium are 1,2 or letter international agreed code for the chemical element, which usually derived from the name of the element.
A binary compound with a more positive or basic element or radical?
In a binary compound, the element that is more positive or basic is typically listed first in the chemical formula. This element is usually a metal or a positively charged ion, while the element listed second is often a nonmetal or a negatively charged ion. The more positive element is usually the one that forms cations in chemical reactions.
How is an element represented in a chemical formula?
Each atom has its own elemental 'symbol' or 'formula', there are more than 92 elements: from number 1. Hydrogen (H) to number 92. Uranium (U). Examples: O for oxygen, C for carbon, N for nitrogen atoms.
