Because eit is a group 1 element . Eg potassium , sodium etc. By Prit Mhala
Silver is, in fact, in group II and therefore has a valency of 2.
1 is the valency of silver
valency of lithium - 1
The valency of iodide is -1
Bicarbonate HCO3- is -1 charge. It has a valency of 1.
Yes, hydroxide has a valency of 1. So sodium hydroxide - NaOH - is a compound with Na having a valency of 1 and hydroxide having a valency of 1. For calcium hydroxide, in which calcium (Ca) has a valency of two (2), the formula is Ca(OH)2.
1 is the valency of silver
valency of lithium - 1
-1 valency
The valency of sodium is +1
AgCl It always has a valency of +1, though it is a transition metal
The valency of iodide is -1
The symbol of Silver is Argentum or Ag and valency is positive 3
The valency of fluorine is -1.
The valency of hydrogen in one.
One is the answer at high school. Silver has a number of valencies:- 1 - the most common, AgCl, AgBr, Ag2O are examples thi is the one to remember! 2 - AgF2 is known 3- Ag2O3 is known
Bicarbonate HCO3- is -1 charge. It has a valency of 1.
Halogens have a valency of -1.
