Metallic atoms hold some of their electrons relatively loosely, and as a result, they tend to lose electrons and form cations. In contrast, nonmetallic atoms attract electrons more strongly than metallic atoms, and so nonmetals tend to gain electrons and form anions. Thus, when a metallic element and a nonmetallic element combine, the nonmetallic atoms often pull one or more electrons far enough away from the metallic atoms to form ions.

Oxyacids are acidic compounds containing at least one oxygen atom. It is the general formula of these acids that helps to distinguish between binary acids and oxyacids; binary acids have the general formula H-X whereas oxyacids have the general formula Common compound names. Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert Write the name of the following ionic compounds. Write the formula for the following covalent compounds. Acetic acid CAS No.

Ionic compounds are compounds composed of ions , charged particles that form when an atom or group of atoms, in the case of polyatomic ions gains or loses electrons. Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules. Molecular compounds are electrically neutral. Ionic compounds are usually formed when a metal reacts with a nonmetal or a polyatomic ion. Covalent compounds are formed when two nonmetals react with each other. Since hydrogen is a nonmetal, binary compounds containing hydrogen are also usually covalent compounds. The charge on the cation is the same as the group number.

This page explains what a transition metal is in terms of its electronic structure, and then goes on to look at the general features of transition metal chemistry. These include variable oxidation state oxidation number , complex ion formation, colored ions, and catalytic activity. The terms transition metal or element and d block element are sometimes used as if they mean the same thing. They don't - there's a subtle difference between the two terms. We'll explore d block elements first:.

A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc. This article contains the list of certain mnemonics in chemistry. Note: After the k shell, they follow alphabetical order skipping s and p as they came earlier. The order of sequence of atomic orbitals according to Madelung rule or Klechkowski rule can be remembered by the following.

Periodic Table of Elements

It consists of an oxygen and hydrogen atom held together by a covalent bond , and carries a negative electric charge. It is an important but usually minor constituent of water. It functions as a base , a ligand , a nucleophile , and a catalyst. The hydroxide ion forms salts , some of which dissociate in aqueous solution, liberating solvated hydroxide ions.

Look at the periodic table ( or the equivalent). Group IV A (14) metals form cations with +4 charge, although tin (Sn) and lead don't form cations. Fe(III) can be used to identify the ion, Fe(III)+3 is just wrong. Once again, a numerical prefix such as di, tri, tetra, and so on, is neither Copper (II) acetate.
