Bond. No, not James Bond
pH and chemical reactions
100
This is found in everything that has mass and occupies space.
What is an ATOM?
100
This carries no electric charge which means it is neutral.
What is a NEUTRON?
100
This is the pH level of pure water
What is pH 7
100
This type of bond is formed when electrons are shared between 2 or more atoms
What is COVALENT BOND
100
This is the range of acidic level
What is pH 1- pH6
200
This is the charge inside the nucleus of an atom, where protons and neutrons are found.
What is POSITIVE
200
electrons carry this type of electrical charge
What is NEGATIVE?
200
Negative ions are always looking for these
What are POSITIVE IONS?
200
Opposites attract. Therefore, this bond is formed between a positive ion and a negative ion
What is IONIC BOND?
200
The speed of chemical reactions is changed by
What are Enzymes
300
These usually share pairs of electron whenever they get the opportunity
What are ATOMS?
300
These are the 3 subatomic particles that can be found inside any atoms
What are PROTON, NEUTRON, and ELECTRON?
300
This is how an atom behaves when its number of protons do not equal its number of electrons
What is UNSTABLE?
300
This is two or more atoms held together by chemical bonds
What is a MOLECULE?
300
This is the term that describes the amount of energy needed to break bonds
What is Bond Energy
400
These move outside of the nucleus in an unimaginable speed.
What are ELECTRONS?
400
This is the smallest of the 3 subatomic particles
What is the electron?
400
This is what is produced after a chemical reaction takes place
What is a product
400
This is how water molecules - oxygen and hydrogen- are formed
What is Sharing Electrons?
400
This term describes the amount of energy needed for a chemical reaction to start
What is Activation energy
500
Atoms are mostly this.
What is EMPTY SPACE
500
This is the number of electron a neutral atom has, if the number of its proton is 5
What is 5?
500
This is the type of chemical reaction that releases energy.
What is Exothermic reaction
500
This is how covalent bond is represented in diagrams
What is solid line
500
During chemical reactions, reactants become products by doing this
What is Breaking and forming bonds?
