consist of a single atom with a positive or negative charge resulting from the loss or gain of one or more valence electrons, respectively.
You are watching: Aluminum is a group 3a metal. which ion does al typically form
a compound that contains one or more hydrogen atoms and produces hydrogen ions (H+) when dissolved in water.
states that in samples of any chemical compound, the masses of the elements are always in the same proportions.
Whenever the same two elements form more than one compound, the different masses of one element that combine with the same mass of the other element are in the ratio of small whole numbers
The charges of the cations of many transition metal ions must be determined from the number of electrons lost.
Write the symbol of the cation and then the anion. Add whatever subscripts are needed to balance the charges.
Write the symbol for the cation followed by the formula for the polyatomic ion and balance the charges.To name a compound containing a polyatomic ion, state the cation first and then the anion, just as you did in naming binary ionic compounds
Use the prefixes in the name to tell you the subscript of each element in the formula. Then write the correct symbols for the two elements with the appropriate subscripts
What does a prefix in the name of a binary molecular compound tell you about the compound’s composition?
A prefix in the name of a binary molecular compound tells how many atoms of an element are present in each molecule of the compound.
Bases are named in the same way as other ionic compounds—the name of the cation is followed by the name of the anion.
An -ide ending generally indicates a binary compound.
An -ite or -ate ending means a polyatomic ion that includes oxygen is in the formula.
Prefixes in a name generally indicate that the compound is molecular.
A Roman numeral after the name of a cation shows the ionic charge of the cation.
In naming a binary molecular compound, the number of atoms of each element present in the molecule is indicated by ____.
When the name of an anion that is part of an acid ends in -ite, the acid name includes the suffix ____.
when naming a transition metal ion that can have more than one common ionic charge, the numerical value of the charge is indicated by a_______
