Atomic Structure Flashcards
(37 cards)
What is the atomic number (smaller number on the periodic table for that element)
The atomic number of an element= the number of protons
The atomic number of an element= number of electrons for a neutral atom
What is an isotope
Isotopes are atoms of the same element with the same number of protons and the same number of electrons but a different number of neutrons
What is the mass number (larger number) of an element
The mass number= the number of protons+ the number of neutrons
What relative charge does a proton have
+1
What relative mass does a proton have
1
Where is a proton located in an atom
Nucleus
What is the relative charge of a neutron
0
What is the relative mass of a neutron
1
Where is the neutron located
Nucleus
What is the relative charge of an electron
-1
What is the relative mass of an electron
1/2000
Where is the electron located
Orbiting around nucleus
What is the relative formula mass of a compound
The sum of the relative atomic masses of the atoms

What is the empirical formula
The empirical formula of a compound is the simplest whole number ratio of elements in a compound
Molecular formula= c2h4
What is the empirical formula
Ch2
What does immiscible mean
Liquids that do not mix together and produce two separate layers
What does miscible mean
Liquids that mix together
What piece of scientific apparatus is used to separate miscible liquids
