Why does the oxygen symbol O not have a subscript?
Because symbols for the elements do not have subscripts. A subscript is added in the chemical formula of a compound to indicate how many atoms of the element are included in a molecule of the compound. For example, when hydrogen (H) and oxygen (O) combine to form water (H2O), a subscript 2 is added to the H to indicate there are two hydrogen atoms in a molecule of water, but no subscript is added to the O, because there is only one oxygen atom is in a molecule of water.
What mineral has a structure and a chemical composition that indicate the conditions under which it formed?
Peat
All of the following features of the ocean indicate tectonic activity except -?
Trenches
Which observation does not indicate that a chemical reaction has occured?
Change in total mass of substances.
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).
What does a subscript on the outside of the brackets indicate?
When a subscripts is found outside the parenthesis it multiplies everything inside the parenthesis Example: Ca(OH)2 -> CaO2H2
What does subscript indicate in chemical formulas?
The number of atoms of the same element in the molecule
What does subscript indicate in a chemical formula?
The number of atoms of the same element in the molecule
What does the subscript indicate in the chemical formula?
The number of atoms of that element in the molecule
In a chemical formula what is used to indicate the number of atoms of each element?
It is called a subscript. For example: In the formula for water (H2O), 2 is the subscript indicating that there are 2 hydrogen atoms in the compound .
how should you indicate that there are multiple polyatomic ions in a chemical formula?
put parentheses around the atoms in the ion and then add a subscript - apex
what number represents the subscript in the formula shown?
The letter or letters that represent an element are called its atomic symbol. The numbers appearing as subscripts in the chemical formula indicate the number of atoms of the element immediately before the subscript. If no subscript appears, one atom of that element is present.
Why does the oxygen symbol O not have a subscript?
Because symbols for the elements do not have subscripts. A subscript is added in the chemical formula of a compound to indicate how many atoms of the element are included in a molecule of the compound. For example, when hydrogen (H) and oxygen (O) combine to form water (H2O), a subscript 2 is added to the H to indicate there are two hydrogen atoms in a molecule of water, but no subscript is added to the O, because there is only one oxygen atom is in a molecule of water.
What are the symbols and numbers called that indicate the atoms in a compound?
Subscript
What does the subscript 2 indicate in the formula?
there are two atoms in the molecule
How should more than one polyatomic ion indicate in a chemical formula?
More than one polyatomic ion should be indicated in a chemical formula by putting parentheses around the atoms in the ions and then adding a subscript.
What does the subscript 2 indicate in the formula O2?
there are two atoms in the molecule
