Which of the following statement is correct with respect to the property of elements with increase in atomic no. in the carbon family?
Their atomic size decreases
Their metallic character decreases
Their ionisation potential increases
Stability of +2 oxidation state increases
The first ionisation potential of Group 13 elements is lower than that of Group 2 elements, because?
Electrons in Group 2 elements are bonded weakly
Electrons in Group 13 elements are bonded tightly
Group 13 elements have 3 electrons in valence shell
Group 13 elements have 5 electrons in valence shell
The metallic character of Group 14 elements
Has no significance
Does not change gradually
Decreases from top to bottom
Increases from top to bottom
Catenation is a process for the formation of
Cations
Ionic compound
Covalent compound
Long chains of identical atoms
Which of the following is not a characteristic of carbon?
Catenation
Multiple bond formation
Availability of d-orbitals for bonding
Highest electronegativity in the Group
Carbon has no tendency to form complex compounds, because of
Its big size
Availability of d-orbital
Non-availability of d-orbital
Its tendency to form covalent compound
