100
Why do elements form bonds?
To have full valence shells to be stable
100
A positively charged ion is called a/an _____.
cation
100
Which element is the MOST electronegative?
Fluorine
100
Does CO2 contain ionic or covalent bonds?
covalent
100
Which group does not tend to form bonds?
Noble gases
200
This bond is when two or more atoms share electrons.
covalent bond
200
A negatively charged ion is called a/an _____.
anion
200
True or False: All elements can have up to eight valence electrons.
False. (ex: hydrogen and helium need only 2, sulfur and phosphorous can hold 10)
200
Does HF contain covalent or ionic bonds?
covalent
200
What determines which type of bond forms between atoms?
Difference in electronegativity
300
The bond formed when two or more atoms transfer electrons.
ionic bonding
300
Alkali metals will always ionize to form ions with a ____ charge.
+1
300
What is the difference between polar and nonpolar covalent bonds?
Polar is unequal sharing while nonpolar is equal sharing.
300
Does Li2O contain ionic or covalent bonds?
ionic
300
Why do ionic bonds form between metals and nonmetals?
The big difference in electronegativity means the nonmetal can completely steal the metal's electron
400
If an atom loses an electron, then that atom will become ____ charged.
positively charged
400
Halogens always ionize to form ions with a ____ charge.
-1
400
Why do nonmetals share electrons instead of transferring them?
They're close in electronegativity values, so neither can completely overpower the other.
400
Would Cl2 have a nonpolar covalent bond or polar covalent bond?
nonpolar covalent bond
400
In a polar covalent bond, there will be an uneven distribution of charge. This means part of the molecule will be more negative than other parts. Would it be more negative towards the more electronegative atom or less electronegative atom?
More electronegative
500
If an atom gains an electron, then that atom will become ____ charged.
negatively charged
500
Alkaline earth metals always form ions that have a ____ charge.
+2
500
Up to how many covalent bonds can form between 2 atoms?
3
500
Would HBr have a polar covalent bond or nonpolar covalent bond?
polar covalent bond
500
How do you draw the ionic bonds in LiF?
600
Which electrons are responsible for the reactivities of the elements?
valence electrons
outermost electrons
electrons in outermost shell
600
Why do the atoms stay together after transferring electrons?
They're oppositely charged, so they attract each other.
600
How do you tell how many bonds a nonmetal is likely to form?
It will form as many bonds as electrons it needs
600
Would H2O be polar or nonpolar?
polar
600
How do you draw the covalent bonds in CO2?
