Why doesnt oxygen have a subscript in the formula H2O?
Oxygen does not have a subscript in the formula H2O because it forms a covalent bond with hydrogen atoms to create a stable molecule. The subscript 2 in H2O indicates that there are two hydrogen atoms bonded to one oxygen atom, making the molecule water.
The 2 in H2O is an example of?
Because one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom.
What does a subscript following a set of parenthesis in a chemical formula indicate?
A subscript following a set of parenthesis in a chemical formula indicates that the entire group enclosed in the parenthesis is to be multiplied by the subscript outside the parenthesis. This is used to show the number of times a group of atoms or molecules is repeated in the compound.
What are used to indicate how many atoms are in a compound?
Subscripted numbers are listed after each element to indicate the number of atoms of that element in the compound. For instance the formula for water is H2O, which indicated that there are 2 hydrogen atoms and 1 oxygen atom (no subscript implies the number 1).
The number of atoms of each element present in the molecule is indicated by what?
The number of atoms of each element present in a molecule is indicated by the subscript to the right of the element symbol in the chemical formula. For example, in H2O, there are 2 hydrogen atoms and 1 oxygen atom.
What is the purpose of a subscript in a chemical equation?
the purpose of a subscript is to tell how many atoms of that chemical is used in the formulaThe number of atoms of the same element in the molecule ~APEX
What does the subscript in a formula tell you?
The subscript in a formula typically indicates the number of atoms of an element present in a molecule. It is used to specify the ratio of atoms in a compound or the number of atoms in a polyatomic ion.
In CF4 what does the subscript 4 mean?
The subscript 4 indicates the number of that type of atoms in the compound. In this case, there are four Fluorine atoms in this molecular compound.
What type of number after a chemical symbol tells how many ato?
The number that follows a chemical symbol is called a subscript. It indicates the number of atoms of that element in a molecule. For example, in H₂O, the subscript "2" indicates there are two hydrogen atoms in each water molecule. If there is no subscript, it is understood to be one atom of that element.
What part of the chemical formula indicates the number of molecules or atoms involved?
The answer is 'subscript'
The subscript in a chemical formula refers to the?
The subscript in a chemical formula refers to the number of atoms of that element present in the molecule. It is a small number written at the lower right of the element symbol. For example, in the formula H2O, the subscript 2 indicates that there are two hydrogen atoms in each water molecule.
What does the subscript mean in the chemical formula?
usually a subscript denotes the number of atoms of a particular element within the formula. ie H2O (the 2 would be a subscript) indicates there are two atoms of hydrogen in one molecule of water.
What type of number after a chemical symbols tells how many atoms of that element are in single molecules?
The subscript number after a chemical symbol indicates how many atoms of that element are present in a single molecule of the compound.
What type of number after a chemical symbol tells how many atoms are in a single molecule?
The subscript, the little number below and after the element, tells how many atoms are in a single molecule.
What type of number after a chemical symbol tells how many atoms of that elements in a single molecule?
The number after a chemical symbol in a chemical formula represents the number of atoms of that element in a single molecule. This number is called a subscript, and it indicates the ratio of atoms in the compound.
In the chemical formula CO2 t6he subscript 2 shows which of the following..?
The subscript 2 shows the number of oxygen atoms in each molecule of the compound, carbon dioxide.
How do you count atoms worksheet?
To count atoms on a worksheet, first identify the chemical formulas present. For each element in the formula, note the subscript that follows it, which indicates the number of atoms of that element. If there is no subscript, it means there is one atom of that element. For compounds with parentheses, multiply the subscript outside the parentheses by the subscripts inside to find the total number of atoms for each element.
