Atomic Structure Flashcards
Which number on an element is the mass?
the top number.
What is the bottom number on an element?
The Atomic (Proton) Number
How do you find the neutron number in an element?
subtract the number of protons with the mass number
What are the protons in an element the same as?
The electrons
What is the relative mass and charge of an electron?
Relatove Mass=Very Small Relative charge=-1
What is the relative mass and charge of a Proton?
Relative mass=1 Relative charge= +1
What is the relative mass and charge of a Neutron?
Relative Mass= 1 Relatove Charge= 0
Where in the atomic structure are the electrons located?
Shells
What is an isotope?
An isotope is one of two or more species of an element
Where are isotopes on the periodic table?
the same place as the original element.
What is similar between isotopes
Protons,electrons,(atomic number) and position in the periodic table.
What s different between isotopes?
Different atomic masses and physical properties along with neutrons.
What is an ion?
A positively/negatively charged atom
What do metals do to get a full outer shell?
lose electrons
What charge ions do metals/any element become when you lose electrons?
A positively charged ion
