What do all elements in one row of the periodic table have in common?

Answer 1

All of the elements in a period (row) have the same number of atomic orbitals also known as Valence Electrons. Every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons. It goes down the Periodic Table like that. At this time, the maximum number of electron orbitals or electron shells for any element is seven.

Answer 2

Do you mean groups (veritcal) or periods (horizontal)? Groups are organized in a way to show the number of valence electrons (number of electrons on outer most energy level) which shows that the chemical properties are similar.

Answer 3

Group 2 elements are Alkaline earth metals

They are all shiny, silvery-white, somewhat reactive metals at STP and readily lose their two outermost electrons to form cations with charge 2+ and an oxidation state, or oxidation number of +2

Answer 4

All elements in one row of the periodic table have the same number of electron shells or energy levels. This means that the elements in the same row share similar chemical properties and reactivity due to the arrangement of their electrons.

Answer 5

Valence electrons and a love for a certain favor of pie

Answer 6

All of the elements in the row have the same number of electron shells.

Answer 7

they all have the same number of core electrons

Answer 8

The elements in same row have same number of shells.The rows are termed as periods.
