What is the cause for vertical periodic trends?

What is the cause for vertical periodic trends?

The elements in groups (vertical columns) of the periodic table exhibit similar chemical behavior. This similarity occurs because the members of a group have the same number and distribution of electrons in their valence shells.

What goes vertical up and down on the periodic table?

COLUMNS run UP and DOWN vertically on the periodic table. A columns is known as GROUP or a FAMILY.

Are Periodic Table periods vertical?

A period is a horizontal row of the periodic table. A group is a vertical row of the periodic table.

Why do periodic trends occur?

Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. These trends exist because of the similar atomic structure of the elements within their respective group families or periods, and because of the periodic nature of the elements.

What is the main cause for all the periodic trends?

The above periodic trends are caused by the interactions of three factors: nuclear charge (the number of protons in the nucleus), the electron shell(s), and the shielding (the effect of the electrons between the outer electrons and the nucleus).

How are the vertical columns in the periodic table called?

The elements are arranged in seven horizontal rows, called periods or series, and 18 vertical columns, called groups.

What are the vertical columns on the periodic table?

How are periods arranged on the periodic table?

Periods in the periodic table. In each period (horizontal row), the atomic numbers increase from left to right. The periods are numbered 1 through 7 on the left-hand side of the table. Elements that are in the same period have chemical properties that are not all that similar.

What are patterns in the periodic table?

Periodic trends are specific patterns in the properties of chemical elements that are revealed in the periodic table of elements. Major periodic trends include electronegativity, ionization energy, electron affinity, atomic radii, ionic radius, metallic character, and chemical reactivity.

What are the vertical columns on the periodic table called?

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 is the name of a vertical column on the table?

Why is the periodic table arranged the way it is?

The Periodic table is shaped due to properties and electron arrangement. Going down each column, you have elements with similar properties, as they have the same number of electrons in their outer shell. How and why is the periodic table arranged? The periodic table of elements arranges all of the known chemical elements in an informative array.

What are the vertical columns going up and down called?

What are the vertical columns going up and down on the periodic table called? COLUMNS run UP and DOWN vertically on the periodic table. A columns is known as GROUP or a FAMILY. All elements in a group or family have the SAME NUMBER of ELECTRONS in the OUTERMOST LEVEL of their electron cloud.

How did Mendeleev organize the elements on the periodic table?

Mendeleev arranged the elements both in terms of their atomic weights and valence. He was also smart enough to leave space for new elements that he thought would be discovered (and he was right!).
