Total questions: 10
Worksheet time: 5mins
What are the two main types of chemical bonds?
Hydrophobic bonds and hydrophilic bonds
Ionic bonds and covalent bonds
Metallic bonds and hydrogen bonds
Van der Waals bonds and polar bonds
What is ionic bonding and how does it occur?
Ionic bonding occurs when atoms repel each other due to similar charges
Ionic bonding is the sharing of electrons between atoms
Ionic bonding is the result of covalent bonds between atoms
Ionic bonding is the electrostatic attraction between oppositely charged ions, and it occurs when one atom transfers one or more electrons to another atom.
What is covalent bonding and how does it differ from ionic bonding?
Covalent bonding involves the attraction of opposite charges between atoms.
Covalent bonding involves the formation of a crystal lattice structure.
Covalent bonding involves the sharing of electrons between atoms.
Covalent bonding involves the transfer of electrons between atoms.
What are the properties of ionic compounds?
Medium melting and boiling points, conductivity in solid state, and the formation of amorphous lattices
High melting and boiling points, conductivity in molten or aqueous state, and the formation of crystal lattices
Low melting and boiling points, non-conductivity in any state, and the formation of gaseous lattices
High melting and boiling points, non-conductivity in any state, and the formation of liquid lattices
What are the properties of covalent compounds?
Formed by sharing of electrons between atoms, low melting and boiling points, usually insoluble in water
Formed by transfer of electrons between atoms, high melting and boiling points, usually soluble in water
Formed by sharing of protons between atoms, high melting and boiling points, usually insoluble in water
Formed by sharing of electrons between atoms, high melting and boiling points, usually soluble in water
What are some examples of substances that form ionic bonds?
Carbon dioxide, water, nitrogen gas
Iron, copper, aluminum
Hydrochloric acid, sulfuric acid, nitric acid
Sodium chloride, magnesium oxide, calcium fluoride
What are some examples of substances that form covalent bonds?
Oxygen, nitrogen, hydrogen
Water, methane, carbon dioxide
Iron, copper, silver
Sodium chloride, sulfuric acid, ammonia
How do you determine the type of bond formed between two atoms?
By counting the number of electrons
By looking at the color of the atoms
By measuring the size of the atoms
By seeing if it is a metal and a nonmetal or 2 nonmetals
What is the difference between polar and nonpolar covalent bonds?
Nonpolar covalent bonds have unequal sharing of electrons.
Polar covalent bonds have equal sharing of electrons.
Polar covalent bonds have unequal sharing of electrons.
Polar covalent bonds have no sharing of electrons.
What is the name for a positively charged ion?
anion
ion
cation
plus ion
