Valency of Elements on the Periodic Table You may assume thevalencesof the chemical elements—the number of electrons with which an atom will bond or form—are those that can be derived by looking at the groups (columns) of the periodic table. While these are the most common valences, the...
These elements combine with different atoms to form heteronuclear molecules, meaning that different nucleuses come together to form compounds. But like all things, there is an exception to the rule. In this case, these exceptions are called diatomic elements. In the Greek language, di refers to...

Group 3A primarily consists of metal elements, with the exception of boron, which is a metalloid. Metalloids can be thought of as elements with a weak metallic character. They are capable of conducting electric and thermal energy, but not as well as most metals can. Metals are always elec...
Process for the extraction of elements with variable valency from waste waterA method for stripping pollutant metals from sewage waters from ore-treatment installations is disclosed, which comprises the step of using, in a short-circuited electrode system through which the waters to be purified are ...

called the atomic mass number. While theatomic numberalways stays the same. Some elements have atoms with different atomic mass numbers. This is because some elements have a different number of neutrons in the nucleus. Versions of an element with different atomic mass numbers are called isotopes....

(~~~) 6.4.1 Introduction Borane chemistry began in 1912 with A. Stock’s classic investigations,(’O) and the numerous compounds prepared by his group during the following 20 y proved to be the forerunners of an amazingly diverse and complex new area of chemistry. During the past few ...
