What do you do if there is only one atom of an element in a formula?
You do not write a subscript because it is understood to be one. For example, the formula for water, H2O, indicates that there are two hydrogen atoms and one oxygen atom in a molecule of water. There is no subscript written next to the oxygen atom because it is understood to be one.
What are two things you cannot do to a subscript in a chemical equation?
1. You cannot change the subscript just to help you balance the equation. You can only balance an equation by using whole-number coefficients written at the beginning of a substance. 2. If no subscript is present, you can't just add one to help you balance the equation for same reason listed above.
A pure substance that is composed only of identical atoms is classified as?
An element. Elements are pure substances that consist of only one type of atom.
What is a pure element saltwateraluminum foilor rose quartz?
A pure element is an also known as a chemical element. Pure elements consist of only one type of atom. Aluminum is the only pure element in the group.
The only nonmetal element that is a liquid at room temperature is?
Bromine is the only nonmetal element that is a liquid at room temperature.
What is implied when there no subscript on a element?
When there is no subscript on an element, it is implied that one atom of that element is present. For example, "H" would represent one atom of hydrogen.
What subscript number is used when there is only one atom of an element present?
None.
What does it mean if an atom has no subscript in a chemical formula?
There is one atom of that element in the molecule.
What does it mean if a chemical symbol in a chemical formula has no subscript?
There is one atom of that element in the molecule.
What is difference between coefficient and a subscript?
The coefficient applies to all of the elements in the compound whereas the subscript applies to only the select elements; unless the subscript follows parenthesis, in which case it applies to all elements inside. ==========================================================Hope it helped! Thanks for voting!
What does it mean when an element in a chemical formula does not have a subscript?
The meaning is that only one atom of this element exist in the molecule. Example: sodium chloride - NaCl.
What does it mean when a symbol is not by a subscript?
It means there is only one of that kind of atom in the molecule.or there is one of that kind of element or compound!
Does an oxygen molecule contain carbon?
No. Oxygen is an element and contains only oxygen atoms. Its formula is O2 (where the 2 is a subscript).
What is the purpose of a subscript in a chemical formula?
The subscript tells you how many atoms of a certain element are in the representative particle of that substance. For example, H2O means 2 hydrogens and 1 oxygen. (The absence of a subscript means there's just 1.) The subscript only applies to the element immediately before it, unless the subscript occurs outside a set of parentheses, in which case it applies to everything inside the parentheses.
What tells how many and atoms form a compound?
a subscript found at the bottom right of the letters in the compound. if there is no number, that indicates there is only one of that element, or atom.
What do you do if there is only one atom of an element in a formula?
You do not write a subscript because it is understood to be one. For example, the formula for water, H2O, indicates that there are two hydrogen atoms and one oxygen atom in a molecule of water. There is no subscript written next to the oxygen atom because it is understood to be one.
Is carbon being affected when there is a subscript of 3 in CO3?
NO. The subscript of 3 applies only to the oxygen (O) in CO3.
