you are actually going by the group number on top of the Periodic Table. example Hyrogen is in group one which means it has one valence. another example Si is in group 4 which means it has 4 valences. just remember each group # equal the amount of valences. Good luck

How would you find valence electrons in a periodic table?
To find the number of valence electrons of an element using the periodic table, you can look at the group number of the element. The group number indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on.
How many valence electron chlorine have?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
How many electrons are in the valence shell of francium?
Francium has one valence electron, its atomic no is 87 and it belong to Ist group of periodic table.
How many outermost electrons do lithium and potassium have?
Both lithium and potassium are in Group I of the Periodic Table, so they both have one valence electron.
What elements on the periodic table have one valence electron?
Elements with one valence electron include hydrogen (H), lithium (Li), sodium (Na), potassium (K), and francium (Fr) in Group 1 of the periodic table.
How many valence electrons does group 1 in the periodic table have?
it has one valence electron
What is the number of valence electrons in family 1A of the periodic table?
One valence electron.
What is the number of valence electron for all the elements in periodic table group 1A 1?
Group 1A (1) elements in the periodic table all have 1 valence electron. This includes elements like hydrogen, lithium, sodium, and potassium.
How would you find valence electrons in a periodic table?
To find the number of valence electrons of an element using the periodic table, you can look at the group number of the element. The group number indicates the number of valence electrons.

What is group in periodic table?
In the periodic table, group indicates the number of valence electrons in the outermost shell. E.g. Group I- the elements in that group have one valence electron in the outermost shell.
Why is the alkali metals the first in the periodic table?
Because they have one valence electron each.
How are the elements in group 1A on the periodic table similar?
They all have one valence electron.

This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
How many valence electron chlorine have?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
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 many electrons are in the valence shell of francium?
Francium has one valence electron, its atomic no is 87 and it belong to Ist group of periodic table.
How many outermost electrons do lithium and potassium have?
Both lithium and potassium are in Group I of the Periodic Table, so they both have one valence electron.
