Elements that are in the same horizontal (left to right) rows, have similar outer shells.
Same row: the same number of electronic shells.
Same column: the same number of electrons on the last (outermost) valance shell.
Electron affinity, Ionization Energy and Valency Radius
elements in the same row are similar because they have the same number of electrons in the outer most shell
They have the same outer energy level, which is the period number.
they have the same shell
Both Ni and Tc are d-block elements (or transition metal elements)
Elements that have similar chemical properties occupy the same group on the Periodic Table.
a family is a column of elements a period is a row of elements
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
They have the same number of valence electrons, or electrons in the outer electron shell. This allows them to react with certain elements.
They are the same
They have the same Valency
Their valence electrons are in the same energy level.
they have the same number of outer electrons
they all have the same electrons.
Both Ni and Tc are d-block elements (or transition metal elements)
There is a group of elements in the periodic table as the elements with same properties are clubbed together.
Elements in the same family (group) on the periodic table have the same number of valence electrons and hence they have similar properties and reactivities.
Elements that have similar chemical properties occupy the same group on the Periodic Table.
a family is a column of elements a period is a row of elements
Elements in a given group have the same number of valence electrons and hence they have similar properties.
they all have the same number of core electrons
