IPC Unit 3 Lesson 7
Check the element pairings that are likely to react with each other. Refer to the periodic table for assistance.
- Rb and Br - Li and Cl - Fr and Cl
Choose all that describe noble gases.
- monatomic - inert
Which group do halogens react with the most?
Group 1 because they have one valence electron that the halogens need to be stable.
Why do atoms want 8 valence electrons?
Having eight electrons will cause the outer energy shell to be full.
not reaching with another element or object
Inert
an element that has only one atom
Monatomic
energy emitted in the form of radiation by unstable elements
Radioactivity
What does halogen mean?
Salt Former
Why are halogens the most reactive nonmetal group?
They have 7 valence electrons.
Why are noble gases the least reactive nonmetal group?
They have 8 valence electrons.
