All Types Of Bonding Flashcards
What is ionic bonding?
Ionic bonding is the electrostatic attraction between oppositely charged ions.
What type of elements typically form ionic bonds?
Ionic bonds typically form between metals and non-metals.
True or False: In ionic bonding, electrons are shared between atoms.
False
What is covalent bonding?
Covalent bonding is the sharing of electron pairs between atoms.
Which type of elements usually participate in covalent bonding?
Covalent bonds usually form between non-metal atoms.
Fill in the blank: In covalent bonding, atoms achieve a full outer shell by ________ electrons.
sharing
What is metallic bonding?
Metallic bonding is the attraction between metal ions and delocalized electrons.
True or False: Metals have high melting and boiling points due to metallic bonding.
True
What is a characteristic property of ionic compounds?
Ionic compounds typically have high melting and boiling points.
What is the result of a covalent bond between two hydrogen atoms?
The result is a hydrogen molecule (H2).
Define polar covalent bond.
A polar covalent bond is a type of bond where electrons are shared unequally between atoms.
What is the difference between a single, double, and triple covalent bond?
A single bond involves one pair of shared electrons, a double bond involves two pairs, and a triple bond involves three pairs.
Fill in the blank: Metals can conduct electricity due to the presence of ________ electrons.
delocalized
What type of bond is formed between sodium (Na) and chlorine (Cl) in sodium chloride (NaCl)?
Ionic bond
True or False: Ionic compounds conduct electricity in solid form.
False
What is the octet rule?
The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.
What type of bond is present in water (H2O)?
Covalent bond
What is a coordinate bond?
A coordinate bond is a covalent bond in which both electrons come from the same atom.
How does a metallic bond contribute to the malleability of metals?
The delocalized electrons allow metal ions to slide over each other without breaking the bond.
Fill in the blank: In a polar molecule, one end is ________ charged and the other end is ________ charged.
partially, partially
What is a common property of covalent compounds?
Covalent compounds usually have lower melting and boiling points compared to ionic compounds.
What is the bond angle in a water molecule (H2O)?
Approximately 104.5 degrees.
True or False: Ionic compounds are usually soluble in water.
True
What is the significance of electronegativity in bonding?
Electronegativity determines how strongly an atom attracts electrons in a bond.
What type of bond is formed in oxygen gas (O2)?
Double covalent bond
Fill in the blank: The ________ model explains the behavior of electrons in metallic bonding.
sea of electrons
