Periodic Trends

Front

What factor affects Coulombic attraction in atoms of the same group?

Back

Distance from the nucleus.

Front

What is electronegativity?

Back

The ability of an atom to attract electrons from another atom.

Front

Which element has the greatest electronegativity: Nitrogen (N) or Arsenic (As)?

Back

Nitrogen (N).

Front

As the Coulombic attraction increases, what happens to the atomic radius?

Back

The atomic radius decreases.

Front

As the Coulombic attraction in an atom increases, what happens to the energy needed to remove an electron?

Back

The energy needed to remove an electron increases.

Front

Define effective nuclear charge.

Back

The net positive charge experienced by an electron in a multi-electron atom.

Front

How does effective nuclear charge affect atomic size?

Back

Higher effective nuclear charge leads to a smaller atomic size.

Front

What is the trend of electronegativity across a period in the periodic table?

Back

Electronegativity increases across a period from left to right.

Front

What is the trend of atomic radius down a group in the periodic table?

Back

Atomic radius increases down a group.

Front

What is ionization energy?

Back

The energy required to remove an electron from an atom.
