Do elements in the same period behave the same?
Elements in the same period have the same number of electron shells; moving across a period (so progressing from group to group), elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.
Are groups or periods more similar?
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
What do elements in the same period group have in common?
Like PERIODic table.). All of the elements in a period have the same number of atomic orbitals. For example, 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.
What’s the difference between groups and periods on the periodic table?
Groups and periods are two ways to categorize elements in the periodic table. Groups are columns of elements, while periods are rows of elements. Groups and periods are two ways to categorize elements in the periodic table. Groups are columns of elements, while periods are rows of elements. Menu Home
Why do elements in the same group have similar properties?
Home Science Chemistry. Elements in the same group of the periodic table have similar properties because their electronic configurations have the same number of electrons in the outermost shell.
Why are there more elements in a period?
Elements in a period share the highest unexcited electron energy level. There are more elements in some periods than others because the number of elements is determined by the number of electrons allowed in each energy sub-level.
Why are elements in the same column on the periodic table inert?
Elements that lie in the same column on the periodic table (called a “group”) have identical valance electron configurations and consequently behave in a similar fashion chemically. For instance, all the group 18 elements are inert, or noble gases.
