These are the patterns of the periodic table across the period.
1. The atomic radius reduces as we move across a period from left to right,
2. The ionization energy increases as we move across a period.
3. The electron affinity decreases as we move across a period.
Learning them enables us to have a clear view of elements in the periodic table.
No, you do not have to memorize the entire periodic table for your chemistry exam. However, you should be familiar with the trends and patterns within the table.
one should look for predictable changes and patterns
The term "periodic" in the periodic table refers to the repeating patterns of chemical and physical properties of elements that occur across each period (row) in the table. This periodicity is based on the number of electrons in the outer energy level of the elements.
No, you do not need to memorize the entire periodic table for chemistry. It is more important to understand the trends and patterns within the table and how elements interact with each other. Familiarity with the table can be helpful, but it is not necessary to memorize every element.

There are many patterns on the Periodic Table! They are in order by family, class, and atomic number. If you look up the periodic table, you will most likely find many more!
it's called the periodic table obviously

a Periodic Table organises the different elements, according to the atoms' mass, type, properties, reactivity etc. See the question about: periodic table patterns
For example the elements from the group 1 of the periodic table.
The vertical columns on the periodic table are groups. Groups show patterns in ionization energies, electronegativity and atomic radius.
we use the periodic table because it helps us with the atoms and electrons it tells us the mass number atomic number and the symbol
