The nucleus of an atom represents most of an atom's mass.
it represents where the atoms, protons, Atomic Mass, atomic number, and electrons where they are located on the nucleus.
All the atoms in the visible universe - about 10E85 grams.
negatively charged and takes up most of the atoms space Takes up most of the atoms mass and is negatively charged
its not D
The number on the periodic table representing the mass in grams of one mole of atoms in an element is called the molar mass, which is expressed in grams per mole. It is numerically equal to the atomic mass in atomic mass units (amu) of the element.
it represents where the atoms, protons, Atomic Mass, atomic number, and electrons where they are located on the nucleus.
All the atoms in the visible universe - about 10E85 grams.
The nucleus.
Atoms atomic number represents their number of protons.
The mole is the atomic weight expressed in grams.
More then 99% of an atoms mass is in the nucleus.

Sigificance of the Symbol of an Element :- 1. Symbol represents name of the element. 2. Symbol represents one atom of the element. 3. Symbol also represents one mole of atoms of the element. That is, symbol also represents 6.022 x 1023 atoms of the element. 4. Symbol represents a define mass of the element (equal to Atomic Mass expressed in grams).
mass of protons + mass of neutrons
The mass of an atom is concentrated in the nucleus (protons+neutrons).
