Most of the mass of the atom is where?
More then 99% of an atoms mass is in the nucleus.
What does most of the atoms mass come from?
the nucleus
Where is most of an atoms mass?
Inside the nucleus.
Does most of the mass in atoms due to electrons?
no
What is atoms mass most made up off?
mass of protons + mass of neutrons
What is most of the atoms mass?
The mass of an atom is concentrated in the nucleus (protons+neutrons).
Is mass used as a method of counting atoms?
Mass is not used as a method of counting atoms directly. Instead, the atomic mass unit (amu) is used to measure the mass of individual atoms relative to the mass of a carbon-12 atom. The mole is the unit used to count atoms, with 1 mole containing Avogadro's number of atoms.
What is true of an atoms's nucleus?
negatively charged and takes up most of the atoms space Takes up most of the atoms mass and is negatively charged
How can you tell the mass of most of the atoms of a given element?
The mass numbers are given on the periodic table.
What makes up nearly all of the atoms's mass?
The sum of all Protons and Neutrons.
Which is our most abundant elements in the body?
In number of atoms (element) hydrogen is the most abundant, not in mass.
Most calcium atoms have an atomic number of 20 and a mass number of 40 but some calcium atoms have a mass number of 48 What word could you use to describe these two kinds of calcium atoms?
Isotopes. Calcium atoms with a mass number of 40 represent the most common isotope, while those with a mass number of 48 are a less common, but still natural, isotopic form of calcium.
