What symbol do scientists use to represent atomic mass unit?
Scientists use the symbol "u" to represent atomic mass unit.
Do carbon and oxygen have the same atomic mass?
They don't contain the same number of particles because some particles are more dense than others making one atom and another atom the same mass but not have the same number of particles.
What does subatomic particles contribute to the value of atomic mass and atomic number?
protons is the same number as the atomic number always and protons plus the average number of neutrons makes up the atomic mass
Is atomic mass and molar mass similar and mass number of particles the same?
Atomic mass and molar mass are similar concepts but not the same. Atomic mass refers to the average mass of an atom of an element, while molar mass is the mass of one mole of a substance. The mass number of particles can be the same in certain cases, such as isotopes of the same element which have the same number of protons and different numbers of neutrons.
Nitrogen has an atomic mass of 14 and an atomic number of 7 so the number of neutrons must be?
The atomic mass of an atom is the total mass of its particles. The atomic number is the number of protons in the atom's nucleus. To find the number of neutrons in an atom, we take its atomic mass (the total mass of its particles) and subtract its atomic number (the number of protons and electrons in the atom). A: Lithium has an atomic mass of 7 and an atomic number of 3 so the number of neutrons is equal to 4. (7 - 3 = 4)
What does the number represent in platinum-195?
It represents the atomic number and atomic mass. Mass number is the superscript Atomic number is the subscript
What symbol do scientists use to represent atomic mass unit?
Scientists use the symbol "u" to represent atomic mass unit.
What is the mass number of copper?
AMU (Atomic Mass Unit) is the SI masses of particles for nucleus.
Do carbon and oxygen have the same atomic mass?
They don't contain the same number of particles because some particles are more dense than others making one atom and another atom the same mass but not have the same number of particles.
What does subatomic particles contribute to the value of atomic mass and atomic number?
protons is the same number as the atomic number always and protons plus the average number of neutrons makes up the atomic mass
What does the decimal number in an element key represent?
atomic mass
What does the atomical number represent?
The Atomic Mass is the mass (weight) of the element measured in atomic mass units (AMU)
What do the numbers and letters in the periodic table represent?
either mass or protons the top is the atomic number it shows how many protons the bottom number is the atomic mass also the weight
What are the particles that make a atom including the atomic number and mass number?
The atomic number is the number of protons in an atom (which equal the number of electrons present) The atomic mass is the number of protons+neutrons in an atom
Which term is used to describe the way the mass of subatomic particles is described?
Atomic Mass units =]
