ionic and covalent compounds
What type of bond is formed when electrons are transferred from one atom to another?
An ionic bond.
Why are molecular Models used?
to show how atoms are arranged in a molecule.
Which family of elements is known as "Noble Gases"?
Group 18
What happens to electrons during ionic bonding?
Electrons are transferred from one atom to another.
What happens to electrons during covalent bonding
Electrons are shared between atoms.
Which type of compound typically has higher melting and boiling points, ionic or covalent compounds?
Ionic compounds.
what model uses balls and sticks?
ball-and stick model.
What is a characteristic of elements in the alkali Metals family?
They are highly reactive and some have one electron in their outer shell
what type of ions are formed in ionic bonding?
Positive ions (Cations) and negative ions (anions).
which type of elements typically form covalent bonds?
Nonmetals.
what is a key property of covalent compounds that distinguishes them from ionic compounds?
covalent compounds often have lower melting and boiling points and do not conduct electricity in their solid or liquid state.
what does the space-filling model show?
the size of atoms in a molecule.
Which family of elements is known for forming salts when combined with metals?
Halogens (group 17)
Which type of elements typically form ionic bonds?
metals and nonmetals.
What is the result of a covalent bond?
A molecule is formed by the sharing of electrons.
Name one example of an ionic compound and one example of a covalent compound?
Ionic compound: Sodium chloride
Covalent compound: water (H2O)
what is a bond angle?
the angle between two bonds in a molecule.
which family contains elements that are generally good conductors of electricity and heat?
Transition Metals.
What is the result of attraction between ions in an ionic bond?
The formation of a strong electrostatic force that holds the ions together.
What is a common property of covalent compounds?
They usually have low melting and boiling points.
why do ionic compounds conduct electricity when dissolved in water but not in their solid state?
In water, ionic compounds dissociate into ions, which can move freely and carry an electric charge.In the solid state, the ions are fixed in place within the lattice structure and cannot move.
How does a lewis structure help with molecular Models?
it shows how electrons are arranged, which helps build the model.
What is a key feature of the elements in the alkali Earth Metals family?
They have two electrons in their outer shell and less reactive than alkali metals.
Why do ionic compounds have high melting and boiling points?
Because of the strong electrostatic forces between the oppositely charged ions.
What is a covalent bond between two atoms of the same element called?
A non-polar covalent bond.
