Honors Unit 6: Ions and Periodic Trends Test Review - 24-25

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

Which element has the lowest electronegativity?

Back

Rubidium has the lowest electronegativity among the elements.

Front

What is atomic radius?

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

Which element has the smallest atomic radius?

Back

Selenium has the smallest atomic radius among the given options.

Front

What is the atomic number of an element with 20 protons?

Back

The atomic number of an element is equal to the number of protons, so it is 20.

Front

What is a cation?

Back

A cation is a positively charged ion, formed when an atom loses one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion, formed when an atom gains one or more electrons.

Front

How does the atomic radius change across a period in the periodic table?

Back

The atomic radius generally decreases across a period from left to right due to increasing nuclear charge.

Front

How does the atomic radius change down a group in the periodic table?

Back

The atomic radius generally increases down a group due to the addition of electron shells.

Front

What is the trend of electronegativity in the periodic table?

Back

Electronegativity increases across a period from left to right and decreases down a group.
