Covalent compounds worksheet formula writing and naming of chemical compounds

A prefix is used in front of each element name to indicate how many atoms of that element are present: 1.

covalent compounds worksheet formula writing and naming of chemical compounds

The first element in the formula is simply listed using the name of the element. Therefore, the atoms form covalent bonds. NaHCO3 sodium hydrogen carbonate or sodium bicarbonate The prefix bi- implies an acidic hydrogen: thus, NaHCO3 is sodium bicarbonate or sodium hydrogen carbonate ; NaHSO3 is sodium bisulfite or sodium hydrogen sulfiteetc.

Prefixes derived from Greek stems are used to indicate the number of each type of atom in the formula unit Table 2.

If both elements are in the same group, the element closer to the bottom of the column is named first. In many cases, two elements can combine in several different ways to make completely different compounds.

Naming ionic and covalent compounds worksheet

If both elements are in the same group, the element closer to the bottom of the column is named first. Numerical subscripts are used if there is more than one of a particular atom. The formula is written with the more electropositive element the one further to the left on the periodic table placed first, then the more electronegative element the one further to the right on the periodic table. The second element is named as if it were a monatomic anion in an ionic compound even though it is not , with the suffix -ide attached to the root of the element name. If both elements are in the same group, the one with the higher period number is named first. The element farthest to the left in the periodic table is usually named first. However, polyatomic ions are held together by covalent bonds, so this compound contains both ionic and covalent bonds. In many cases, two elements can combine in several different ways to make completely different compounds. The order of the elements in the name of BrF3, bromine trifluoride, is determined by the fact that bromine lies below fluorine in Group Identify the number of each type of atom present. A prefix is used in front of each element name to indicate how many atoms of that element are present: 1.

Naming binary two-element covalent compounds is similar to naming simple ionic compounds. Binary Inorganic Compounds Binary covalent compounds—covalent compounds that contain only two elements—are named using a procedure similar to that used for simple ionic compounds, but prefixes are added as needed to indicate the number of atoms of each kind.

The order of the elements in the name of BrF3, bromine trifluoride, is determined by the fact that bromine lies below fluorine in Group Table 2.
