Chemical bonding
Cards in this deck (19)
- 1Chemical BondingA strong attractive
force that exists between certain atoms in
a substance. - 2Born-Haber CycleEnergies involve in forming ionic compounds.
- 3Lattice energyThe energy
needed to separate an ionic solid
into isolated ions in the gas
phase. - 4CationPositive charged ion occurs when atom loses electron (s).
- 5AnionNegative charged ion occurs when atom gains electron (s).
- 6Isoelectronic ionIons that have equal number of electrons hence they have identical electron configurations.
- 7What is the chemical bond between metal + non-metal combination?Ionic bond
- 8Combination of non-metal + non-metal atoms creates____________compound.covalent
- 9Describe ionic bondAn ionic bond is a chemical bond formed by the electrostatic attraction between positive and negative ions.
- 10Write Lewis symbols for the following elements: Al, I, Se, Ar
- 11—
- 12Give formula and name of ionic compound formed by combination of Mg and Br.
- 13What is the formula of ammonium sulphate?
- 14Describe covalent bondA chemical bond formed by the sharing of a pair of electrons between atoms.
- 15Three types of covalent bond using different number of shared electrons.single, double and triple bonds.
single bond: 2 shared electrons.
double bond: 4 shared electrons.
triple bond: 6 shared electrons. - 16What is Bond length?The distance between nuclei at the minimum potential energy i.e. the most stable.
- 17What is Bond energy?The amount of energy required for breaking the bond i.e. to separate the two atoms linked by covalent bond. This is also called “bond dissociation energy”.
- 18What is coordinate covalent bond?A coordinate covalent bond is a bond formed when both electrons of the bond are donated by one atom.
- 19What is Electronegativity?An ability of an atom to draw bonding electrons to itself.
