What is an Ionic bond?
the strong electrostatic forces of attraction between oppositely charged ions
the strong electrostatic forces of attraction between similar charged ions
the strong electrostatic forces of attraction between opposite atoms
the strong intermolecular forces of attraction between positive ions and electrons.
What is the term for electrons and proton?
charged ions
negatively charged ions and positively charged ions
metal ion and sea of delocalised ions
All of the above
How many electrons are being shared by each ELEMENT?
(a)
Which are covalent properties?
low boiling point
doesn't conduct electricity
dissolve in water
volatile
Which of these are properties of ionic compounds?
high boiling point
soluble in oil
conducts electricity when molten and solid
soluble in water
What are the giant covalent compounds you have to know?
Graphite
Diamond
Silicon dioxide
silicon trioxide
Why is there no electrostatic attraction in a covalent substance?
Cause covalent bonds shares electron
cause electrostatic attraction only occurs when opposite ions are held together
cause there is no charge distribution
Cause covalent bonds have a weak intermolecular forces of attraction
What are the uses of Diamond?
drilling
cutting
jewellery
trading
Why are ions charged?
An atom can be a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less than the number of protons in the atom.
An atom can acquire a positive charge or a negative charge depending on whether the number of proton in an atom is greater or less than the number of electrons in the atom.
An atom can acquire a positive charge depending on whether the number of electrons in an atom is greater than the number of protons in the atom.
An atom can acquire a negative charge depending on whether the number of electrons in an atom is less than the number of protons in the atom.
Define a covalent bonding
It’s when 2 non-metal atoms react together and share their electrons to achieve a stable shell.
It’s when 2 non-metal atoms react together and exchange their electrons to achieve a stable shell.
It’s when 2 metal atoms react together and share their electrons to achieve a stable shell.
It’s when 2 opposite atoms react together and share their electrons to achieve a stable shell.
What type of covalent bond is this? (not the name of the product)
(a)
What material is used as a lubricant?
Silicon
graphite
HCl
diamond
Why are metals malleable and ductile?
It has layers and can slide over each other
It has weak ionic bonds allowing it to break easily
Because enough heat energy is applied
All of the above
What elements are involved in Ionic Bonding?
(a)
How are silicone dioxide and diamond similar?
Malleable and ductile
have free moving electrons
High boiling points
forms covalent bond to 4 other atoms
Metals bond together by having a strong ________ force of attraction between ______ ions and the sea of ____________.
intermolecular.........metal.........protons
electrostatic..........positive......electrons
electrostatic.........negative......delocalised electrons
electrostatic.........positive......delocalised electrons
Why does graphite conduct electricity whereas diamond doesn't?
It has a free moving electron
cause the electrons remains still
Cause there are less protons in graphite
cause graphite is weak
Which is a metallic bonding?
Which of these compounds do you need to know?
ammonia ion
hydrogen peroxide ion
hydroxide ion
sulfuric acid ion
sulfate ion
which phrase/word is defined be "A regular arrangement of alternating positive and negative ions"
Attraction
Magnets
Lattice
Opposite charges attracts
