What r monvalent metals?
Are they metals that have only one possible ion charge?
Any other information would be greatly appreciated, thanks
Sorry, I meant mono; not mon
Monovalent metals are those that have a +1 charge (divalent metals have a +2 charge and trivalent metals have a +3 charge).
Thank you:-)
naahhh naahhh suppa man no heaaah!
Monovalent metals are metals that have only one possible ion charge. In other words, they can form only one type of positive ion when they lose electrons in a chemical reaction. This is because they have a fixed number of valence electrons that are easily lost to achieve a stable electron configuration.
Some examples of monovalent metals include:
1. Group 1 metals or alkali metals: Lithium (Li+), Sodium (Na+), Potassium (K+), Rubidium (Rb+), Cesium (Cs+), and Francium (Fr+)
2. Group 2 metals or alkaline earth metals: Beryllium (Be2+), Magnesium (Mg2+), Calcium (Ca2+), Strontium (Sr2+), and Barium (Ba2+)
It is worth noting that there are metals with variable charges, which means they can form multiple types of positive ions with different charges. These are called polyvalent or multivalent metals. Examples include Transition Metals like Iron (Fe2+ or Fe3+), Copper (Cu+ or Cu2+), and Chromium (Cr2+ or Cr3+).
To determine whether a metal is monovalent, you can refer to the periodic table to check the group number. Group 1 metals are always monovalent, whereas group 2 metals are always divalent. That way, you can identify the possible ion charges for a given metal.
