Generally speaking, the column or "group" usually defines the number of valence electrons an atom has, ignoring the transition metals, lanthanides and actinides. Valence electrons are the electrons available for use in bonding and not in a completed electron shell. The row or "period" really doesn't say much about valence electrons or electrons in general, as you go down the rows the atoms get larger (speaking of atomic weight) and thus have more electrons.
This is hard to explain, sorry if it is vague for you, but I will try to make it clear.
The way you can find the number of energy shells is by looking at the ROWS of the Periodic Table of Elements.

Do you see the numbers on the far left side right underneath "Period Number"? Those are the numbers of energy shells!
The period number in the periodic table tells you the number of electron shells or energy levels for an element. Each period corresponds to the number of electron shells an element's atoms have.
You can find how many electrons are there by looking at the atomic number.
The atomic number of the elements are generally mentioned in the periodic table. The atomic number of an element is same as the number of protons / electrons in a neutral element.

How many electron cloud does chlorine have?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
What are the periods in the periodic table?
The periods in the periodic table refer to the horizontal rows that indicate the number of electron shells an element's atoms have. There are 7 periods in the periodic table, each corresponding to the number of electron shells found in elements within that period.
Which way does electron shells increase on the periodic table?
Electron shells increase in number as you move down a group in the periodic table. This is because the principal quantum number (n) increases for elements in the same period.
What can the period of a element be determined by?
The period of an element in the periodic table can be determined by the number of electron shells or energy levels that the element's atoms have. Each period on the periodic table corresponds to the number of electron shells occupied by the elements within that period.
What does the P stand for on the periodic table?
The "P" on the periodic table stands for "Period." Periods are the horizontal rows on the periodic table that indicate the number of electron shells present in an atom of an element.
The organization of the periodic table is based on what?
The Periodic Table is organized by Atomic Number (the number of protons) and the Electron Shell capacity (the number of electrons).

The periods in the Periodic Table have the same number of what?
They have the same number of electron shells.
How are the elements arranged?
Elements are arranged on the periodic table based on their atomic number, which is the number of protons in their nucleus. This arrangement groups elements with similar properties in columns called groups or families, while elements in the same period have the same number of electron shells.
When you read the periodic table top to bottom the number of electron energy level increase or decrease?
When reading the periodic table top to bottom, the number of electron energy levels increase. This is because each row in the periodic table corresponds to one electron energy level. The number of energy level corresponds to the period number of the element.
What are the periods in the periodic table?
The periods in the periodic table refer to the horizontal rows that indicate the number of electron shells an element's atoms have. There are 7 periods in the periodic table, each corresponding to the number of electron shells found in elements within that period.
Which way does electron shells increase on the periodic table?
Electron shells increase in number as you move down a group in the periodic table. This is because the principal quantum number (n) increases for elements in the same period.
Which number tells you the number of valence electron?
Indirectly this can be derived from the number of the group in the periodic table.
How are the number of electron in the outer level and columns of the periodic table related?

Is snow on the periodic table?
No, snow is not on the periodic table. The periodic table is a chart that organizes elements based on their atomic number, chemical properties, and electron configurations. Snow is a form of precipitation that consists of ice crystals.
What can the period of a element be determined by?
The period of an element in the periodic table can be determined by the number of electron shells or energy levels that the element's atoms have. Each period on the periodic table corresponds to the number of electron shells occupied by the elements within that period.
How many electron rings are found in each period of the periodic table?
The number of electron rings in each period of the periodic table corresponds to the period number. For example, in the first period (row), there is only one electron ring; in the second period, there are two electron rings, and so on.
