periodic properties

How are elements on the periodic table arranged by?

• in alphabetic order
• simular physical & chemical properties
• their symbols
• Just simular physical properties

Amphoteric oxide

• Na2O

• MgO

• Al2O3

• P2O5

The measure of an atom's attraction to electrons

• Electronegativity

• Ionization

• Atomic radii

In which of the following the energy change

corresponds to first ionisation potential only:-

• X(g) ⎯→ X

  +

  (g) + e ̄

• X2(g) ⎯→ X

  +

  (g) + e ̄

• X(s) ⎯→ X

  +

  (g) + e ̄

• X(aq) ⎯→ X

  +

  (aq) + e ̄

Among the elements given below, the element with the least electronegativity is:

• Carbon

• Fluorine

• Boron 

• Lithium

Among the following which one has the highest cation to anion size ratio?

• CsI

• CsF

• LiF

• NaF

Among the elements Ca, Mg, P and Cl, the order of increasing atomic radii is

• Mg < Ca < Cl< P

• Cl<P<Mg <Ca

• P < Cl< Ca < Mg

• Ca <Mg <P<Cl

HORIZONTAL ROWS

• groups

• periods

• tables

• field

• A

• B

• C

• D

As you move across a row (period) on the periodic table, the atomic radius ______________________

• Increases

• Decreases

• Stays the same

• Explodes
