Chapter 6/7 Review

Front

What is electromagnetivity and how does it change on the periodic table?

Back

Electronegativity increases as you move from left to right across a period on the periodic table.

Front

What is the periodic law?

Back

The periodic law states that when elements are arranged according to increasing atomic number, there is a periodic repetition of their chemical and physical properties.

Front

What are the elements in group 3 through 12 called?

Back

Transition elements.

Front

How many valence electrons does nitrogen have?

Back

Nitrogen has 5 valence electrons.

Front

Why do elements in the same group have similar chemical properties?

Back

Elements in the same group have the same number of valence electrons.

Front

What is the atomic number?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What are alkali metals?

Back

Alkali metals are the elements in group 1 of the periodic table, known for being highly reactive and having one valence electron.

Front

What are noble gases?

Back

Noble gases are the elements in group 18 of the periodic table, known for their lack of reactivity due to having a full valence shell.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

What is the trend of ionization energy across a period?

Back

Ionization energy generally increases as you move from left to right across a period.
