What is a periodic trend look like on the periodic table?
Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element’s properties.
What does trends mean on 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 trend do you see as you move down the periodic table?
Atoms get bigger as you go down a column on the periodic table. This is because in going down a column you are jumping up to the next higher main energy level (n) and each energy level is further out from the nucleus – that is, a bigger atomic radius. Atoms get smaller as you go across a row from left to right.
What makes a periodic trend?
A periodic trend is a regular variation the properties of an element with increasing atomic number. A periodic trend is attributed to regular variations in the atomic structure of each element.
What is a table trend?
A trend is generally “it gets bigger” or “it gets smaller” sort of thing. All our trends describe the trend in two directions on the periodic table: 1) across a row, and 2) up and down a column. Here are the important ones for us.
What appears to be the trend in electronegativity as you move down a column?
On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group. As a result, the most electronegative elements are found on the top right of the periodic table, while the least electronegative elements are found on the bottom left.
