chemistry 2.1.1-2.2.2 Flashcards
What is the atomic number ?
The atomic number is the number of protons in the nucleus.
What is the mass number
The mass number is the total number of protons and neutrons in the atom.
What is a isotope
Why do isotopes have the same chemical properties but different physical traits
Isotopes are atoms of same element with the same number of protons, but different numbers of neutrons
Isotopes have similar chemical properties because they have the same electronic structure. They may have slightly varying physical properties because they have different masses.
What is the definition of isotopic mass
Relative Isotopic mass is the mass of one isotope compared to one twelfth of the mass of one atom of carbon-12
What is the definition of relative atomic mass
What is the definition of relative atomic mass
What is the definition of relative atomic mass
Relative atomic mass is the weighted mean mass of one atom compared to one twelfth of the mass of one atom of carbon-12
What is the two calculation to calculate relative abundance mass
R.A.M= = (isotopic mass % abundance) 100
R.A.M= = (isotopic mass relative abundance) total relative abundance

What is a mole
What is a mole
The mole is the amount of substance in grams that has the same number of particles as there are atoms in 12 grams of carbon-12
