This type of chemical bond involves the EQUAL sharing of electrons:
What is a NON-POLAR COVALENT bond
100
Atoms can have very different properties on their own than they do when combined in chemical bonds. Can you provide an example of this?
What is SODIUM CHLORIDE
100
This explains why oxygen gains a partial negative charge when combined with hydrogens to form water:
What is that OXYGEN IS MUCH MORE ELECTRONEGATIVE
100
This property of water involves water molecules bonding to basically anything they can form hydrogen bonds with -- which also explains why your hair stays wet for so long after a shower:
What is ADHESION
200
This is a pure substance, made of only ONE kind of atom:
What is an ELEMENT
200
These subatomic particles have NO charge:
What are NEUTRONS
200
Because of its significant water content, Earth was long ago given this nickname:
What is THE BLUE PLANET
200
This type of bond is formed when an electronegative atom from one molecule is attracted to an H from another, separate molecule:
What is a HYDROGEN BOND
200
This property of water is caused by cohesion, and explains how it's possible to float a paper clip in a beaker of water:
What is SURFACE TENSION
300
This type of chemical bond involves the SHARING of electrons between atoms:
What is a COVALENT bond
300
This refers to atoms that have the same number of protons, but different numbers of neutrons:
What are ISOTOPES
300
Of all the water on planet earth, this percentage is saltwater:
What is 97%
300
This property of water involves water molecules being attracted to other water molecules, which helps explain the phenomena of water "doming" when drops are placed on a coin:
What is COHESION
300
This property of water thankfully exists, otherwise ice would sink, causing the oceans and ultimately our planet to freeze over:
What is that ICE IS LESS DENSE A SOLID THAN AS A LIQUID
400
This type of chemical bond involves the TRANSFER of electrons from one atom to another:
What is an IONIC bond
400
These subatomic particles circle the nucleus:
What are ELECTRONS
400
Of all the water on planet earth, this is the amount that is 1) Freshwater that is 2) available to us:
What is LESS THAN 1%
400
This property of water explains why, despite absorbing large amounts of heat, the oceans of the world do not rise in temperature that much:
What is WATER'S HIGH HEAT CAPACITY
400
This property of water is a combination of cohesion and adhesion, and explains how water can defy gravity to move from the ground to a forest canopy:
What is CAPILLARY ACTION
500
When an atom takes on a charge, whether positive or negative, that atom becomes this:
What is an ION
500
This type of chemical bond involves the UNEQUAL sharing of electrons between atoms:
What is a POLAR COVALENT bond
500
Because of the unequal sharing of electrons in a water molecule, the molecule is said to be this:
What is POLAR
500
Every single chemical reaction that takes place in your body, takes place in water. This explains why water is referred to as this:
What is THE UNIVERSAL SOLVENT
500
When a solution is being prepared, this is the substance that is "being dissolved" (sugar, etc.):
