Fill in the blank: Covalent bonds form between a ____________ and a ______________.
a)
nonmetal and a metal
b)
metal and a metal
c)
nonmetal and a nonmetal
2.
Pick out the correct definition of covalent bonding and ionic bonding.
a)
Covalent bonding is when two atoms split from each other, because the electrons repel each other. Ionic bonding is when two atoms share electrons with each other.
b)
Covalent bonding is when two atoms give away a few of their electrons, while ionic bonding is bonding only between electrons located on the same group in the periodic table.
c)
Covalent bonding occurs only between atoms, in means, of taking the amount of electrons they need, while ionic bonding is about sharing electrons and joining atoms together.
d)
Covalent bonding is when two atoms share electrons with each other to complete their outer shells, while ionic bonding is when atoms convey electrons to create bonds.
3.
What is a chemical formula and why do you use in chemistry?
a)
A chemical formula is a chemical equation used to represent the number of atoms present.
b)
A chemical formula is a scientific formula, which you normally use to solve for a specific variable. It is necessary to follow by this formula, otherwise you won't be able to count the # of atoms.
c)
A chemical formula is a set of chemical symbols, describing the number of elements in a specific compound.
4.
In an ionic bond, electrons are ______.
a)
taken to keep stability.
b)
lost or gained to keep stability.
c)
shared to keep stability.
d)
single, double, or triple to keep stability.
5.
In a covalent bond, electrons are ________.
a)
shared between each other to keep both sides happy.
b)
always kept, and there is never a time when atoms lose or gain electrons
c)
gained at all times
d)
lost at all times
6.
What happens when atoms gain or lose electrons?
a)
When atoms gain electrons, it means that they becomes negative ions. When atoms tend to lose electrons, they become neutral ions.
b)
When atoms lose electrons, they become neutral ions. When atoms gain electrons, they become positive ions.
c)
When atoms gain electrons, they become negative ions. And, when atoms lose electrons, they become positive ions.
7.
What frequent patterns are found between ionic and covalent bonds when tested with different physical properties?
a)
Ionic bonds all react differently from one another, and covalent bonds never follow the same pattern when tested with different physical properties.
b)
Ionic bonds follow common patterns when you check their reactions for various physical properties, and covalent bonds stick together, and react similarily to one another, too.
8.
What is the purpose of covalent bonds between atoms?
a)
The purpose of covalent bonds is so atoms can lose electrons, until they vanish out of existence.
b)
The purpose of covalent bonds is so atoms can gain stability by fighting over their elements, to get what they want.
c)
The purpose of covalent bonds is so atoms can have full outer shells.
9.
What are the ionic compounds combined for chemical formulas: Li (subscript-2) O and K (subscript-3) N?
a)
The answer for #1 would be Lithium Oxide and the answer for #2 would be Aluminum Oxide.
b)
The answer for #1 would be Calcium Oxide, and the answer for #2 would be Lithium Neon.
c)
The answer for #1 would be Potassium Sulfide, and the answer for #2 would be Calcium Nitride.
d)
The answer for #1 would be Lithium Oxide, and the answer for #2 would be Potassium Nitride.
10.
What are three significant rules when naming ionic compounds?
a)
The anion always goes first, before the cation. You can use any name for the monatomic cation, and a monatomic anion receives its name by taking the first part of a name and adding -ide to the end.
b)
The cation always goes before the anion when naming ionic compounds, the monatmoic cation obtains the same, common name as its parent name, and a monatomic cation receives its name by taking the last part of a name and adding -ied at the end.
c)
The cation always gets put first in the name, before the anion. Monatomic cations receive its name from its parents, and a monatomic anion acquires its name by taking the first part of a name and adding -ide to the end.
11.
What is the name for the following ionic compound: Li (subscript-3) N?
a)
Trilithium neon
b)
Calcium sulfide
c)
Monolithium nitride
d)
Trilithium nitride
12.
What are the three types of covalent bonds you can create?
a)
A single bond, an octet bond, and a polar bond
b)
A double bond, a triple bond, and a covalent bond
c)
A single bond, a double bond, and a triple bond
13.
In covalent bonds, what do you use to indicate the number of atoms in each element?
a)
Suffixes
b)
Chemical formulas
c)
Scientific equations
d)
Prefixes
14.
What two components are ionic compounds made up of?
a)
catons and covalent bonds
b)
cations and valence electrons
c)
cations and anions
15.
What is an atom's oxidation number?
a)
It determines the number of atoms an element has.
b)
It determines the charge of an element.
c)
It explains the number of electrons shared between atoms.
