Name the following ions: (a) Ba 2+ (b) Cs + (c) V 3+ (d) HCO 3 - (e) NH 4 (f) Ni 2+ (g) NO 2 - (h) ClO 2 - i) Mn 2+ (j) ClO 4 -

Hey everyone, we're being asked to identify either the name or the formula for each of the following pairs. So starting off with our first one were given no 3 -. So this is going to be our nitrate ion. And if we had n no two minus, this one would be our nitrite ion. So as we can see right here, R n 02 minus has the ending of ICT. And our nitrate has the ending of A. T. E. And the only difference is that we added that one oxygen. Now moving on to our next one, we have foss fight ion. So this is going to be P and same concept. So we have P 033 - for foss fight. So for phosphate, that must mean we have P 043 -. So we're adding that extra oxygen When we have that 80 e ending. Now, lastly looking at O H minus, we know this is our hydroxide ion since we have our hydrogen and our oxygen. So I hope this made sense. And let us know if you have any questions

Chapter 2, Problem 153

Name the following ions: (a) Ba²⁺ (b) Cs⁺ (c) V³⁺ (d) HCO₃^- (e) NH₄ (f) Ni²⁺ (g) NO₂^- (h) ClO₂^- i) Mn²⁺ (j) ClO₄^-

Verified step by step guidance

Identify the type of ion: cation or anion.

For cations, use the element name followed by the charge if necessary (e.g., transition metals).

For anions, use the root of the element name with the appropriate suffix (e.g., -ide, -ate, -ite) or use the common name if it's a polyatomic ion.

For polyatomic ions, refer to a list of common polyatomic ions to find the name.

Combine the information to name each ion: (a) Barium ion, (b) Cesium ion, (c) Vanadium(III) ion, (d) Bicarbonate ion, (e) Ammonium ion, (f) Nickel(II) ion, (g) Nitrite ion, (h) Chlorite ion, (i) Manganese(II) ion, (j) Perchlorate ion.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Ionic Charge

Ionic charge refers to the electrical charge that an ion carries, which results from the loss or gain of electrons. Cations are positively charged ions formed by losing electrons, while anions are negatively charged ions formed by gaining electrons. Understanding the charge is crucial for naming ions correctly, as it influences the ion's nomenclature and its behavior in chemical reactions.

Common Ion Names

Common ion names are standardized names used to identify ions based on their elemental composition and charge. For example, Ba2+ is known as barium ion, while ClO4- is called perchlorate ion. Familiarity with these names helps in accurately communicating chemical information and understanding the roles of different ions in compounds and reactions.

Polyatomic Ions

Polyatomic ions are ions composed of two or more atoms covalently bonded together, which collectively carry a charge. Examples include HCO3- (bicarbonate) and NO2- (nitrite). Recognizing polyatomic ions is essential for naming compounds and understanding their chemical behavior, as they often participate in various chemical reactions and form part of larger molecular structures.
