What does atomic mass represent of an element represent?
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
What does the atomic mass of an atom represent?
The atomic mass of an atom represents the average mass of an atom of that element, taking into account the relative abundances of its isotopes. It is measured in atomic mass units (amu) and is usually found on the periodic table below the element's symbol.
Do subscripts represent the relative mass of each type of atom in the compound?
No, subscripts in a chemical formula represent the number of atoms of each element in the compound. The relative mass of each atom is accounted for by the atomic mass of the element found in the periodic table. So, atomic mass, not subscripts, gives you the relative mass of each type of atom in a compound.
What does the mass number in helium represent?
The mass number in helium represents the total number of protons and neutrons in the nucleus of a helium atom. It is used to determine the mass of the atom and differentiate between different isotopes of helium.
What do the superscript and subscript mean in the notation 40 K represent 19?
The superscript (40) represents the mass number, which is the total number of protons and neutrons in the nucleus of the atom. The subscript (19) represents the atomic number, which is the number of protons in the nucleus of the atom. Therefore, in the notation 40 K represent 19, the atom is potassium with a mass number of 40 and an atomic number of 19.
