Question

What trend in atomic radius do you see as you go down a group/family on the periodic table? What causes this trend? What trend in atomic radius do you see as you go across a period/row on the periodic table? What causes this trend? Circle the atom in each pair that has the largest atomic radius. a) Al B b) S O c) Br Cl d) Na Al e) O F f) Mg Ca Put the following elements in order from smallest to largest atomic radius and explain why: C, O, Sn, Sr. Rank the following elements by increasing atomic radius: carbon, aluminum, oxygen, potassium. Circle the atom in each pair that has the largest atomic radius. a) Al B b) Na Al c) S O d) O F e) Br Cl f) Mg Ca Define electronegativity How does the ionic radius of a nonmetal compare with its atomic radius? What trend in electronegativity do you see as you go down a group/family on the periodic table? What causes this trend? What trend in electronegativity do you see as you go across a period/row on the periodic table? What causes this trend?

Explanation / Answer

Question 1 AND

Question 2

Atomic radius in group--------------INCREASES

Question 3

AND

Question 4

Atomic radii decrease from left to right across a period.

DECREASES ACROSS ---

Period because the net nuclear charge increases

Nuclear size step by step diminishes from left to appropriate over a period of elements. . This is on account of, inside a period or group of components, all electrons are added to a similar shell. In any case, in the meantime, protons are being added to the core, making it all the more decidedly charged. The impact of expanding proton number is more noteworthy than that of the expanding electron number; thusly, there is a more prominent atomic fascination. This implies the core draws in the electrons all the more firmly, pulling the molecule's shell nearer to the core. The valence electrons are held nearer towards the core of the iota. Subsequently, the n the atomic radius diminishes.
