Answer:
The valence electrons increase is not the trends in the properities of the elements of a group.
Explanation:
The periodic table can predict the properties of new elements, because it organizes the elements according to their atomic numbers.
Physical properties are used to observe and describe matter.
Appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity and many others are the physical properties of the element.
Reactivity with other chemicals, toxicity, coordination number, flammability, enthalpy of formation, heat of combustion, oxidation states, chemical stability and etc. are the chemical properities.
The elements are arranged based on atomic numbers and electron configurations

1.The properties of an element depends in the periodic table depends on its
A. Atomic size
B. Atomic mass
C. Electronic configuration
D. No of proton
Its answer is C but why not also D because I think it depends on also atomic no?

2.What is periodicity in properties of elements with reference to modern periodic table? Why do all elements of same group have similar properties? How does the tendency of elements to gain electrons change as we move from left to right in the periods?
