bonding Flashcards
write 1- or -1 in a charge of an element
false, just input -
if the subscript of two elements in ionic bonding is the same or divisible by the same number, what should we do?
simplify
in ionic bonding, we should use these to separate the element from the other and the subscript
parenthesis
in IB, what process are we gonna do?
- know the charge of each element.
- criss-cross.
- use parenthesis.
- simplify if needed.
Al^3 + OH
Al(OH)3
ionic bonding is a bond between?
metal and non-metal
the charge of a metal is as is.
true
what suffix should be used in replacing the name of an element?
-ide
Give the name: FeI3
Iron (III) Iodide
Chromium(III) Arsenide
CrAs
Cobalt (III) Sulfide
Co2S3
Ra3N2
Radium Nitrate
in naming (transition metals), writing (II) is accepted only if the element [e.g. palladium (II), palladium (IV)]. while (I) is not necessary.
true
non-metal + non-metal
covalent bonding
what are the 3 types of bond in CB?
- single
- double
- triple
more electrons, more _____?
strong bond
what are the elements that are only allowed in CB?
Hydrogen, elements belong to the stair, non-metals, Xe, no noble gases
covalent bonding uses LEDS.
true
high electronegativity, less attraction for electrons
false
low electronegativity, less attraction for electrons
true
doesn’t produce charge, but share the same electrons?
covalent bonding
higher electronegativity
terminal
central
lower electronegativity
electronegativity from the right is?
increasing
