The elements in the first row of the Periodic Table are called the "noble gases." This row includes helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). These gases are characterized by their lack of reactivity due to having a full valence shell of electrons. They are typically colorless, odorless, and exist as monatomic gases under standard conditions.

A horizontal row of elements is called a?
On the Periodic table, horizontal rows are given the technical term "periods", while vertical columns are called "groups". Elements in the same period are similar in that they have the same number of energy levels.
