What do chemical formulas tell you the number of?
A chemical formula tells you the number of each type of atom in the molecule or structure.
What tells what elements a compound contains and the exaxt number of each element in a unit of that compound?
a chemical formula
What does the group number of A elements (in the AB numbering system) tell about valence electrons?
The group number of A elements in the AB numbering system tells you the number of valence electrons that element has. Elements in the same group have the same number of valence electrons, which determines their chemical properties.
What does periodic table tell you?
The periodic table tells you chemical elements. :)
What two things does a chemical formula tell us about a compound?
the actual number of atoms in a molecule
What is an elements number that tells you the number of protons in its nuceus?
The element's atomic number.
What tells you the number atoms of each elements?
atomic number
What does a chemical formula tell you about a pure substance?
It tells you the elements and the proportions of those elements that are present to make the pure substance.
What three things does a chemical formula tell you?
The type and the number of atoms of each element present.
What does the atomic number tell us?
The atomic number tells us the number of protons in the nucleus of an atom. It determines the element's identity and its place on the periodic table. Elements with different atomic numbers have different chemical properties.
What does an elements atomic number tell you?
It tells you the number of protons in the nuclei of its atoms.
What do the formula of a chemical equation tell you?
The formula of a chemical equation tells you the type and number of atoms or molecules involved in a chemical reaction. It helps to balance the equation to ensure that mass is conserved and the reaction follows the law of conservation of mass.
