What is an ion?
An atom that has gained/lost electrons. A charged particle.
What is an isotope?
An atom with the same amount of protons and electrons but different amounts of neutrons.
What charge does a proton have?
+1
What mass does a proton have?
1
What charge does an electron have?
-1
What mass does an electron have?
NEGLIGIBLE
What charge does a neutron have?
0
What mass does a neutron have?
1
What ions do group 1 form?
+1
What ions do group 7 form?
-1
Does group 3 lose or gain electrons to form an ion?
LOSE
How would you find the number of electrons, protons and neutrons in an atom using the periodic table?
Electrons= atomic number, protons=atomic number, neutrons= atomic mass-atomic number
True or False: Isotopes of an element have the same chemical properties as the element
TRUE
What are the steps involved in drawing the electronic structure of an atom?
Chemical symbol, period=shells, groups= electrons in outer shell, first shell has two electrons, any other shells will have 8
What does the period number tell us about the electronic structure of an element?
How many electron shells the element will have
What does the group number tell us about the electronic structure of an element?
How many electrons will be in the outer shell
