Example : Cl F
Both Chlorine and flourine have the same electronegativity ( almost) as they both belong to same group.
The number of electrons in the penultimate shell of the element with valency -1. ... Occurrence of characteristic properties of elements takes place at definite intervals in the modern periodic table....
the law that the properties of the elements are periodic functions of their atomic numbers. Also called Mendeleev's law. (originally) the statement that the chemical and physical properties of the elements recur periodically when the elements are arranged in the order of their atomic weights.....
Yes, the given statement is true- Atomic size of an element depends on the nuclear charge of that element. This is because, more nuclear charge means more protons, and more protons can hold more electrons of opposite charge. If there are more electrons in the atom of an element, its atomic size increases......
So, as you move down a group on the periodic table, the electronegativity of an element decreases because the increased number of energy levels puts the outer electrons very far away from the pull of the nucleus. Electronegativity increases as you move from left to right across a period on the periodic table.....
Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other. This attraction is known as an ionic bond........
