What scale is used when judging how acidic or basic a liquid is?
What is the pH scale?
what is ionic bonding?
An Ionic bond is where negative and positive ions attract
Electrons that are already paired on an element are?
What is 'non bonding'
What is all matter made up of?
What are atoms?
There are many types of chemical reactions, but they can always be identified by looking for:
what are
What is the neutral pH measurement
what is 7?
what is a positive ion
what is a cation
What is the most amount of electrons you can use in the second orbital of an atom?
what is 8e-
what element has 2 protons
what is helium
When do synthesis reactions occur?
When different molecules/atoms interact to form a different compound or molecule
What acid does the body contain?
what is hydrochloric acid?
what is a negative ion
what is an anion
What type of diagram would you use for covalent bonding?
What is the 'Lewis Dot Structure'
what does it mean when an atom loses electrons
what is a 'positively charged ion'?
What is an exothermic reaction?
when energy is released
What do we call pH scale under 7?
what is acidic?
To determine the ratio of each ion in an ionic compound, you need to write the charge of the positive metal and negative non metal. Then you ____________ these numbers to work out the formula:
what is 'swap and drop'
As these atoms come together their outer electrons are attracted to the _______ of both atoms and become shared by the atoms.
what is the nucleus?
What does it mean when a atom loses protons?
what is a 'negatively charged ion'?
what is a displacement reaction?
A more reactive element can displace/push a less reactive element out of its compound during a chemical reaction.
What do we call a basic pH scale (8-14)
what is alkaline?
how is an ionic bond formed
what is the 'octet rule' and 'losing and gaining electrons'
how are covalent bonds formed
when non metal atoms react with each other
what is the law of conservation of mass?
Matter can't be destroyed or created during a chemical reaction, only rearranged
What is a decomposition reaction
The breaking down of substance to form 2 or more new substances
