Chemistry - Atomic Structure Flashcards
Where are the Alkali Metals?
Alkali Metals (Group 1)
Where are the Halogens?
GROUP 17
Where are the Transition Metals?
Transition Elements or Transition Metals
The element Sodium can be found in Group 1 of the Periodic Table.
What is the other name given to this group?
Alkali Metals
What are sub-atomic particles?
Subatomic Particles
What’s the name given to Group 2?
Alkaline Earth Metals (Group 2)
What’s the Atomic Number?
The number of protons in the atom.
Where could a student find out information on the element Flourine (F)?
In the Periodic Table of Elements
Where are the Noble Gases?
GROUP 18
Can atoms of two different elements have the same number of protons?
No, all elements have a unique number protons in their atoms.
This is the atomic number
How many neutrons has an iron atom?
30 Neutrons
56 - 26 = 30
Where are the Alkalne Earth Metals?
GROUP 2
O2
chemical formula for oxygen gas
Name an element that has the same number of electrons in its outer shell as Flourine (F)
Chlorine. Bromine
these are the halogens
Identify the element whose atom is shown in the diagram
7 protons** + 7 neutrons = 1**4 (atomic weight)
Name the type of sub-atomic particle that has a positve charge?
Name the type of sub-atomic particle that has a negative charge?
Electrons are negative
What is this group of elements called?
Halogens
What is this group of elements called?
Noble Gases
Name the process which uses electricity to separate water into its elements
Electrolysis
Compare the mass of protons and electrons
A proton is about 1800 times more massive than an electron
Mass Number = 9
Atomic Number = 4
Find the number of neutrons
neutrons = mass number - #protons
mass number = #protons + #neutrons
