Inert, low boiling point, low density and monatonic
1 of 14
What does Inert mean?
Unreactive
2 of 14
What does monatomic mean?
They appear as single atoms instead of compounds
3 of 14
Name three noble gases
Helium, neon, argon, krypton, xenon, radon and Oganesson
4 of 14
What is something noble gases can be used for because of its unreacitivity?
You could use them in lightbulbs because they won't react with the hot filaments.
5 of 14
What are elements in group 7 called?
Halogens
6 of 14
How many electrons are in halogens outer shell?
7, since they are in group 7 in the periodic table
7 of 14
What are four properties of group 7 elements?
7 electrons on the outer shell, they make diatomic molecules, when a metal atom transfers an electron to this atom it turns into a salt and as you go down the group the elemnts get less reactive
8 of 14
Whats diatomic molecules?
molecules made of pairs of atoms
9 of 14
Why do the elements in group 7 get less reactive as you go down the group?
1. Because the atoms gain more electron shells, the outer electon shell is further from the nucleus and the attraction between the electron and the nucleus decreases
10 of 14
How are halogens structured in their elemental form?
Diatomic molecules
11 of 14
Why can chlorine displace bromine from a compound?
It is more reactive
12 of 14
What are two types of displacement?
Subsitution and cannonball
13 of 14
Why do halogens form negative ions?
When they react they gain 1 electron to get a full outer shell, by gaining this electron they become a negative ion
