Atoms Flashcards
Why do atoms have a overall neutral charge?
Atoms have an overall neutral charge because, they have the same number of protons and electrons.
What does soluble mean?
Soluble means something that can dissolve in water.
What the hell are isotopes?
Isotopes are different atoms of the element.
What happens to the reactivity as you go down the groups?
The reactivity increases as you go down the groups.
What’s a mixture?
A mixture is a material that’s made up of more than two or more chemical substances which aren’t chemically bonded.
What do atoms bond to form?
they bond to form molecules
What does solute mean?
Solute means
How do you work out how many neutrons an element has?
atomic number - atomic mass
What is distillation?
Distillation is the process of of separating the components or substances from a liquid mixture by using selective boiling and condensation
How do you calculate the relative atomic mass?
relative atomic mass = (mass number of isotope 1 x percent abundance of isotope 1) + (mass number of isotope 2 x percentage abundance of isotope 2)
