What kinds of positive and negative ions always combine in one to one ratio?
Ions that have the same (for lack of a better word) absolute value of charge. Meaning 1+ and 1- ions will combine in a 1:1 ration (Na+ + Cl- --> NaCl), as will 2+ ions with 2- ions (Mg2+ + SO42- --> MgSO4) and 3+ ions with 3- ions (Al3+ + N3- --> AlN)
Why are prefixes not needed in naming ionic compounds?
Ions combine in only one ratio, so prefixes are not needed.
What ions are present in what ratio in a solution of aqueous calcium chloride?
The ions are: Ca2+ and Cl-; the ratio chloride ions/calcium ions is 2.
What is the ratio of Sr2 plus ions to Br- ions in a neutral compound?
The atomic ratio Sr/Br is 2.
How many hydrogen ions combine with chlorine ion?
One. A hydrogen ion (H+) has a +1 charge, and a chloride ion has a -1 charge, Cl-, so they combine in a 1-to-1 ratio to form a neutral compound, HCl or hydrochloric acid.
In what ratio do calcium and hydroxide ions combine?
One Calcium ion to 2 hydroxide ions.
How many moles of Cl- ions are needed to completely combine with 0.25 moles of Mg 2 ions?
Mg2+ + 2 Cl- are in 1 : 2 ratio (of ions) so also 0.25 : 0.50 mole ratio
Why are prefixes not needed in naming iconic compound?
Ions combine in only one ratio. -APEX

Why are prefixes not needed in naming ionic compounds?
Ions combine in only one ratio, so prefixes are not needed.
Do all ionic compounds have the same ratio of ions?
No. The ratio depends on the charges of the ions.
Substances that release ions that combine with hydrogen ions?
A base.
What is th formula of the compound formed between aluminum ions and phosphate ions?
AlPO4. This is because an aluminum ion has an oxidation number of 3+ and the phosphate ion has an oxidation number of 3- and thus combine in a 1:1 ratio.
What ions are present in what ratio in a solution of aqueous calcium chloride?
The ions are: Ca2+ and Cl-; the ratio chloride ions/calcium ions is 2.
What is the ratio of Sr2 plus ions to Br- ions in a neutral compound?
The atomic ratio Sr/Br is 2.
How element combine?
elements combine because no body noes :DBecause elements become ions then combine
Does the electron configuration denote the ratio of ions in the compound?
No. The formula unit for an ionic compound denotes the ratio of ions in the compound. For example, the formula unit NaCl indicates a ratio of 1 sodium ion to 1 chloride ion, CaCl2 indicates a ratio of 1 calcium ion to 2 chloride ions, and Fe2O3 indicates a ratio of 2 iron ions to 3 oxide ions.
