Metals and non-metals both can have valency 1. Metals which have 1 valence electron and non-metals which have 7 valence electrons, have valency 1. It is because, metals loose their 1e^(-) and non-metals gain 1e^(-) to complete their octet.

Atoms tend to join with other atoms through chemical bonds to enhance their stability. When two atoms bond together, they form molecules. Thus, molecules are a group of atoms that have been held together by chemical bonds. These bonds can either be covalent, ionic bonds, or intramolecular forc...
Why do elements from each family have similar properties even though their periodic trends are different? Why are halogens diatomic while the elements of other groups are polyatomic? Give the reasons for trivalency and monovalency in group 13 elements. Describe why most of th...
Periodic properties and their trends Frequently Asked Questions-FAQs Genesis of Periodic Classification 1. Dobereiner’s Triads German chemist Johann Wolfgang Dobereiner attempted to classify elements with similar properties into groups of three elements each. These groups were called ‘triads’. Dobereine...
During the mid-1860s Meyer took the newly established atomic weights of many elements and arranged them into families that bore similarities in properties, including the ability of an atom to combine with other atoms (valency). In 1869 Mendeleev presented his table of the elements (sixty-three ...
How to find valency of compounds? How do you calculate the coordination number of complex compounds? What are atoms and elements, and how do they differ? Which elements have the most similar chemical properties? Do the properties of an element change when it combines with another element...
Valency:In the periodic table elements the valency increases from one to seven in period with respect to hydrogen but with respect to oxygen it first increases one to four and then decreases to zero. Valancy of sodium, potassium is one. For alkaline earth metals, valency is two and for alum...
Periodic Table of Elements - The periodic table is the tabular arrangement of all the chemical elements on the basis of their respective atomic numbers. In the periodic table, the vertical columns are called groups and the horizontal rows are called peri
