There are certain rules for writing chemical formulas. A chemical formula indicates the masses and mass proportions of the various elements that make up a compound. A binary compound is composed of two distinct elements. The formulae of such compounds are written using valencies. Both kinds of ...
electrovalent and covalent bonds. q3 how many elements are there? currently the periodic table includes 118 elements. some elements were present only in laboratories and in nuclear accelerators. so, you may wonder how many elements of course can be found. the usual response given in the ...
to name covalent compounds... - use same prefixes as hydrates to indicate how many atoms of the element there are (never use mono- on the first element)- change ending of last element to "-ide" to write covalent compound formula... - prefixed indicate subscript of each element- NO NEED...

The GaSe semiconductor compound consists of monoatomic sheets in the sequence Se-Ga-Ga-Se. The intralayer chemical bondings of the atoms are predominantly covalent, while the interlayer forces are relatively weak: these layers are held together via van der Waals forces. Four principal forms of ...
