Metals and Non-Metals Flashcards
Elements that react by losing electrons to form positive ions are…
metals
Elements that do not form positive ions are…
non-metals
What is an ion?
An atom which has become charged through the loss or gain of one or more electron(s)
When do metals form positive ions?
When they react and lose electrons
When do non-metals form negative ions?
When they react and gain elecrtons
What happens when a metal loses electrons?
The atom ends up with more positively charged protons than negatively charged electrons, leaving it with and overall positive charge.
What happens when a non-metal gains electrons?
The atom ends up with more negatively charged electrons than positively charged protons, leaing it with an overall negatve charge.
What happens to the outer shell when you descend down the groups?
The outer shell becomes further away from the nucleus, weakening their attraction to the nucleus.
The further down the group an element is…
the more easily it can react and lose its outer electron(s), for metals
Non-metals are more or less feasible to gain elecrtons
more
What is a key difference between metals and non-metals, talking about outer electrons.
Metals don’t have a lot of outer electrons while non-metals have a lot of outer elecrtons.
How do atoms gain full outer shell electrons?
By reacting to lose or gain sharing electrons.
