What is the Periodic Table?

Back

A tabular arrangement of chemical elements, organized by increasing atomic number, electron configuration, and recurring chemical properties.

Front

What is ionization energy?

Back

The energy required to remove an electron from an atom in its gaseous state.

Front

Which element has a lower ionization energy: Calcium (Ca) or Scandium (Sc)?

Back

Calcium (Ca) has a lower ionization energy than Scandium (Sc).

Front

What are noble gases?

Back

Elements in Group 18 of the periodic table, known for their lack of reactivity due to having a full valence shell.

Front

What is electronegativity?

Back

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

Front

Which group of elements is known as Halogens?

Back

Group 17 elements, including Fluorine (F), Chlorine (Cl), Bromine (Br), Iodine (I), and Astatine (At).

Front

What is the trend of electronegativity across a period?

Back

Electronegativity increases from left to right across a period.

Front

What is the trend of atomic radius down a group?

Back

Atomic radius increases as you move down a group in the periodic table.

Front

What is the significance of the atomic number?

Back

The atomic number represents the number of protons in the nucleus of an atom, determining the element's identity.

Front

What are alkali metals?

Back

Elements in Group 1 of the periodic table, known for being highly reactive and having one electron in their outermost shell.
