What is Electronegativity?

Back

Electronegativity is how good an atom is at attracting electrons.

Front

Which element has a greater electronegativity: Cl or Al?

Back

Cl has a greater electronegativity than Al.

Front

How does electronegativity change across a period?

Back

Electronegativity increases from left to right within a period.

Front

How does electronegativity change down a group?

Back

Electronegativity decreases from top to bottom within a group.

Front

Which element has a greater electronegativity: N or C?

Back

N has a greater electronegativity than C.

Front

What is the trend in atomic radius as you move down a group?

Back

The atomic radius increases as you move down a group.

Front

Which element has a larger atomic radius than Zinc?

Back

Strontium has a larger atomic radius than Zinc.

Front

What is the atomic radius trend across a period?

Back

The atomic radius decreases from left to right across a period.

Front

Define the term 'periodic trend'.

Back

Periodic trends are patterns in the properties of elements that are observed across periods and groups in the periodic table.

Front

What is the relationship between atomic number and electronegativity?

Back

Generally, as atomic number increases, electronegativity increases across a period and decreases down a group.
