Front

As you move down the periodic table, atoms get bigger because ____________.

Back

The atoms have more energy levels.

Front

Which element's atoms are larger? Sodium or Silicon?

Back

Sodium.

Front

Which of the following elements has 7 valence electrons? Sodium (Na), Aluminum (Al), Fluorine (Fl), Calcium (Ca)

Back

Fluorine (Fl).

Front

As you look from left to right across a period, ionization energy and electronegativity both ____________.

Back

increase.

Front

Electronegativity is...

Back

how good an atom is at attracting electrons.

Front

What is the periodic trend for atomic size as you move down a group?

Back

Atomic size increases.

Front

What is the periodic trend for ionization energy as you move across a period?

Back

Ionization energy increases.

Front

What are valence electrons?

Back

Electrons in the outermost shell of an atom that determine its chemical properties.

Front

What is the significance of the octet rule?

Back

Atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.
