Question

what property of an element determines its chemical?
1.protons of an element
2.valency of an element
3.molar mass of an element
4.none of these​

Answer 1

Answer:

The atomic number of an element determines its chemical behaviour.The atomic number gives us the rough idea of the number of protons in the nucleus and electrons present in the shells and how they are distributed.The distribution of electrons in the different shells helps us to predict the valency and thus its chemical behaviour
