6 elements which are
titanium(Ti), Zirconium (Zr), Hafnium(Hf), rutherfordium (Rf), Cerium (Ce), and thorium (Th).
here thorium and rutherfordium are radioactive elements.
I guess, the most fundamental is their valency. This dictates how many times it can bond to other elements. Elements with the same valency often share similar properties with other elements with the same valency. The periodic table is divided into 8 rows (and a D block). Each of these 8 rows have elements with similar properties, related to their valencies.
valency..
The valency of Ammonium (NH4) is +1.
Valency
Transition metals
All 2A elements show the valency of two.
when carbon is not in exited state it has two valency to form the bond. But when it is exited it has four unpaired of electrons. So therefore carbon has a four valency and can form four bonds.
Yes elements with variable valency can be stored in water. example Phosphorus.
Many elements have two or more valences.
helium's valency is zero as id does not combine with other elements

The valency of first four main group elements is equal to their group numbers but elements from Group 5 to 8 have two valencies one equal to group number and second is obtained by subtracting group number from 8.

The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.

valency..
Yes, it is. Since valency is the no. of electrons an element should gain or loose or share to become stable. So, this is true in case of substances which form ions. But elements like carbon never form ions. Its valency is four. It shares electrons to get stable.
