Variation in periodic properties Flashcards
1
Q
Define periodic properties
A
The basic law governing modern periodic table states that the properties of elements are periodic functions of their atomic number. These properties reappear at regular intervals or follow a particular trend at regular intervals.
2
Q
What causes periodicity?
A
The cause of periodicity in properties is the repetition of similar outer electronic configuration after certain regular intervals, and difference in number of shells.
Valency, Atomic Radius, Electronegativity, IP and Electron affinity, altogether are dependent on the configuration of the atom and thus can explain the periodicity.
3
Q
What is atomic size?
A
Radius of the atom, from the center of the nucleus.
