What else can I help you with?
How can you tell how many atoms of each element there are?
You can determine the number of atoms of each element in a compound by using the chemical formula of the compound. The subscripts in the formula indicate the number of atoms of each element. For example, in H2O (water), there are 2 hydrogen atoms and 1 oxygen atom.
Does a chemical formula tell you how many atoms of an element are in a unit of a compound?
yes it does
How many atoms are in a particular element are in a compound?
The number of atoms of a particular element in a compound can vary depending on the chemical formula of the compound. You can determine the number of atoms by looking at the subscripts in the chemical formula. For example, in H2O (water), there are 2 hydrogen atoms and 1 oxygen atom.
How many atoms of an element are in a compound?
a chemical formula is made up two things what are they
How many atoms are there of each element in the compound NO3?
In each molecule of NO3, there is one nitrogen atom and there are three oxygen atoms.
How many atoms of each element make up the compound of CaSO4?
The compound CaSO4 contains 1 calcium atom, 1 sulfur atom, and 4 oxygen atoms.
How is a formula of a compound written?
The formula of a compound is written using the symbols of the elements present in the compound and subscript numbers to represent the ratio of each element in the compound. The subscript numbers indicate how many atoms of each element are present in a molecule of the compound.
What do the prefixes in a covalent compound name tell when writing the chemical formula?
The prefixes in a covalent compound name indicate the number of each element present in the compound. The prefixes are used to determine the subscripts in the chemical formula, specifying how many atoms of each element are bonded together.
What do subscripts tell you about a compound?
This is farely simple. The subscripts just tell you how many atoms of an element are in the compund. Like this: H20 - Water has 2 hydrogen atoms and 1 oxygen atom CO2 - Carbon Dioxide has 1 carbon atom and 2 oxygen atoms. hence the name carbon di(which means 2)oxide(oxygen). The numbers succeeding elements indicate the number of atoms of that particular element in the compound. For example, in H20, there are two hydrogen atoms and one oxygen atom. In H2SO4, there ar two Hydrogen atoms, one Sulfur atom and four Oxygen atoms.
What indicates all the elements in the compound as well as how many atoms of each element are present?
A molecular formula.
Does a subscript tell how many atoms of an element are in a unit of a compound?
Yes. No subscript means that there is just one.
What is importance of naming chemical formula?
A compound is a substance made up of a definite proportion of two or more elements. A chemical formula tells us the number of atoms of each element in a compound. It contains the symbols of the atoms of the elements present in the compound as well as how many there are for each element in the form of subscripts
