What are the 7 trends of 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 are the 4 main trends of the periodic table?
There are four main periodic trends: electronegativity, atomic size, ionization energy, and electron affinity.
What are the 3 trends found on the periodic table?
Periodic trends are patterns in elements on the periodic table. Major trends are electronegativity, ionization energy, electron affinity, atomic radius, and metallic character.
What are the trends of atomic mass on 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 are the trends in the modern periodic table?
Major periodic trends include atomic radius, ionization energy, electron affinity, electronegativity, valency and metallic character. These trends exist because of the similar electronic configuration of the elements within their respective groups or periods and because of the periodic nature of the elements.
How can I remember the periodic table trends?
The periodic trends tell you in which direction of the periodic table do you have increasing values for different chemical properties. The mnemonic is bear: B E A R. And each letter stands for different chemical properties.

Why does atomic mass increase down a group?
So, when the atomic number increases, the mass number of the isotopes is higher (though they are different isotopes), and so the relative atomic mass will increase. Since this occurs as you go down a group, the atomic mass increases as you go down a group.
Does atomic weight increase with atomic number?
The atomic number is what the periodic table is based on. So the atomic number increases with each element. The atomic mass is the sum of the protons and neutrons. As the atomic number increases it causes an increase in the atomic mass.
What is the fastest way to memorize the table of elements?
Memorization Strategies
- Break down the table into sections.
- Spread out the memorization process.
- Learn the elements in a song.
- Make nonsense words made from element symbols.
- Use color to learn element groups.
- Use a mnemonic device to help remember the order of the elements.

What is most important in determining the periodic trends across a period?
The shielding effect and nuclear charge are the two main concepts used to explain the periodic trends down a group or across a period.
Why is it important to understand periodic trends?
One of the reasons the periodic table is so useful is because its structure allows us to qualitatively determine how some properties of the elements vary versus their position on the periodic table. The variation of properties versus position on the periodic table is called periodic trends.
Why does atomic size increase from top to bottom?
The number of energy levels increases as you move down a group as the number of electrons increases. Each subsequent energy level is further from the nucleus than the last. Therefore, the atomic radius increases as the group and energy levels increase. .
Why does atomic size decrease from left to right?
Reason: The nuclear charge is increasing and size of valence shell remains same as we move from left to right. Hence, in any period, the atomic size of the element decreases from left to right.
Does atomic weight increase from left to right?
Explanation: As you go from left to right in the Periodic Table, you are adding more protons and neutrons to the nuclei. The atoms in the rows further down have even more protons and nucleons. Therefore, atomic mass increases from left to right and from top to bottom of the Periodic Table.
What is the relationship between atomic number and atomic weight?
Each atom, therefore, can be assigned both an atomic number (the number of protons equals the number of electrons) and an atomic weight (approximately equaling the number of protons plus the number of neutrons).

What factors affect periodic trends?
There are three factors that help in the prediction of the trends in the periodic table: number of protons in the nucleus, number of energy levels, and the shielding effect.
Does atomic size increase as you go down?
Atomic size increases as you go down a column because of the addition of another electron shell and electron shielding.
Why does atomic size increase as you go left?
Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius.
Why does the atomic mass decrease from left to right?
Reason: The nuclear charge is increasing and size of valence shell remains same as we move from left to right. Hence, in any period, the atomic size of the element decreases from left to right. Q. Atomic size and ionic size decreases in I group elements of the modern periodic table if we move downwards.
