How do you come up with an outermost shell?
The outermost shell of an atom is determined by the number of electrons it can hold, which is based on the atom's position in the periodic table. Atoms tend to fill their outermost shell with electrons to achieve stability, following the octet rule for main group elements. The outermost shell is also known as the valence shell and is responsible for an atom's chemical behavior.
Which group of the periodic table has 3 electrons?
all the members of 3rd A group of periodic table have 3 electrons in outermost shell they are B ,Al, Ga, Tl and In.
Why hydrogen is placed in alkali metals or in first group of modern periodic table?
As with all alkali metals, hydrogen has one electron in its outermost shell.
What type of shell is the outermost energy of a shell of an atom?
The outermost occupied energy shell of an atom is the valence shell, and it varies depending on the atom. It can be determined by looking at the period the atom is in on the periodic table.
Group 1 is called what in the periodic table?
Group 1 in the periodic table is called the alkali metals. These elements are highly reactive and have one electron in their outermost shell. Examples include lithium, sodium, and potassium.
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.
How many electrons on the outermost shell of calcium?
There are 2 electrons on the outermost shell of calcium.
What group of elements have an outermost electron shell that is complete?
Inert gases
How many protons are in the outermost shell of sodium?
no protons, one electron as it is in group I of the periodic table

Why is phosphorus in group 3?
Phosphorus is in group 15 (or group 5A) on the periodic table, not group 3. Group 15 elements have 5 valence electrons in their outermost shell.
How many electron in the outermost shell of phosphorus?
Phosphorus has 5 electrons in its outermost shell. This means it belongs to group 15 of the periodic table and has a valence electron configuration of 3s^2 3p^3.
How do 3a differ from other group of elements?
The group 3 of the periodic table include lanthanides and actinides.
How many electrons does potassium have on its outer shell?
Potassium has one electron on its outer shell. It belongs to group 1 of the periodic table, so it has one electron in its outermost shell.
How many electrons are in the outermost level of argon?
There are 8 electrons in the outermost level of argon, which is known as the valence shell. Argon is in group 18 of the periodic table, so it has a full valence shell with 8 electrons.
Which group of the periodic table has 3 electrons?
all the members of 3rd A group of periodic table have 3 electrons in outermost shell they are B ,Al, Ga, Tl and In.
What element is a S?
the elements belonging to group 1 and 2 of the Periodic Table are s-block elements. it includes elements in which the outermost subshell is s and that have 1 or 2 electrons in their outermost shell.
