100
It is the tendency of an atom to want to gain an electron.
What is electronegativity?
100
All of the elements in this family have 6 valence electrons, will gain 2 electrons, and become +2 cations, to become stable.
What is group 16?
100
It is the smaller volume of a mixture that is dissolved.
What is solute?
100
Because of this characteristic of water blood is great at delivering nutrients to cells throughout one's body.
How does the fact that water is a "universal solvent" support life? Why is it important?
100
A covalent bond in which the electrons are shared equally.
What is non-polar covalent bond?
200
The electrons in an atom's outer-most shell.
What are valence electrons?
200
This is the only family in the periodic table that is both neutral and stable at the same time.
What is group 18/ the Noble gases?
200
A bond that occurs between atoms because electrons are transferred.
What is an ionic bond?
200
This type of bond will form between atoms from families 1& 2 and families 6 & 7.
What are ionic bonds?
200
The bonds occur between atoms that have similar and high electron affinities. Electrons are shared.
What are covalent bonds?
300
They show the symbol of an element with one dot for each of the element's valence electrons.
What are Lewis Dot structures?
300
All of the elements in this family achieve stability by giving away one valence electron and becoming +1 cations.
What is group 1/ Earth Metals?
300
1) Draw the Lewis Dot structures 2) Show the transfer of electrons 3) Show the resulting ions 4) Show the compound
What are the 4 steps for drawing and ionic bond?
300
These bonds occur between atoms that have opposite electron affinities.
What are ionic bonds?
300
A covalent bond in which the electrons are not shared equally.
What is a polar covalent bond?
400
When the number of protons = the number of electrons.
What is neutral?
400
It is the substance of greater volume in a mixture that does the dissolving.
What is a solvent?
400
The cation keeps its name, and the anion gets an "ide" suffix.
What is the convention for naming ionic compounds?
400
1) Draw the Lewis Dot structures 2) Draw lines for pairs of shared electrons 3) Draw the resulting molecule
What are the steps for showing a covalent bond between atoms?
400
It is the property of water that explains why it is possible that we have tall trees. It occurs because Hydrogen bonds occur between water molecules.
What is cohesion?
500
When an atom's outermost electron shell is full.
What is stable?
500
To determine it for an element you must consider the number of valence electrons it has when neutral, and how many electrons can fit in its outermost shell.
What is electronegativity?
500
These inter-molecular attractions occur between water molecules because each water molecule is polar covalent.
What are Hydrogen bonds?
500
It is the characteristic of a water molecule that happens because Oxygen has a high electron affinity and Hydrogen has a medium electron affinity.
Why is water a polar covalent molecule?
500
This happens because the polar negative Oxygen atoms of water molecules surround the positive solute ions, and the polar positive Hydrogen atoms of water molecules surround the negative solute ions.
Why is water a good solvent of any solute with a charge (polar or ionic)?
