cations in a compound are always positive.
NaO
No, It shows the formulas of 2 compounds, neither of which are binary. a binary compound is a single compound made of only 2 elements. Each of the compounds above has 3. What is shown are the reactants with balanced coefficients for the acid- base reaction of NaOH and H2SO4
By combining three calcium cations with charges of +2 each with two phosphate anions with charges of -3 each to give a formula unit Ca3(PO4)2.
silver sulphate/sulfate has the chemical formula of Ag2SO4. this means that there is 2 atoms of silver one atom of sulphur/sulfur and 4 oxygen in each molecule of the compound. this means there are 3 different elements in the compound.
Carbon dioxide is a compound of carbon and oxygen. It a gas, slightly soluble in water when it forms (the weak) hydro-carbonic acid. When pressurised and cooled its solid state is called 'dry ice'.
These cations may be derived from different chemical elements.
experimentation
No.Water is a binary compound. A binary compound contains two elements, regardless of the number of atoms of each.
No, cations have a positive charge and have lost electrons. Anions have a negative charge and have gained electrons. In an ionic compound anions and cations attract each other due to opposite charges.
yes each have a charge of 1.
The cations and anions are specific for each salt.
NaO
The number of atoms in each element .
No, It shows the formulas of 2 compounds, neither of which are binary. a binary compound is a single compound made of only 2 elements. Each of the compounds above has 3. What is shown are the reactants with balanced coefficients for the acid- base reaction of NaOH and H2SO4
This number is different for each cation.
Sodium Oxide Na2O is ionic. Each formula unit includes two sodium cations and one oxide anion.
There is no such thing as dialuminum trioxide because the combination of 2 aluminums and 3 oxygens creates an IONIC COMPOUND, since it is between a metal and nonmetal, and ionic compounds are not named the same way as binary molecular compounds which is the way it is named in the question. In naming a binary molecular compound you denote each element with the number of each atom in the formula, which was done with " dialuminum trioxide", except this molecule is NOT a binary molecular compound, but an IONIC COMPOUND. To name an ionic compound you simply drop the ending to the least metallic element (oxygen) and add an -ide. So the outcome is ALUMINUM OXIDE.
