The elements within a group have a similar number of?

The elements within a group have a similar number of valence electrons. This results in comparable chemical properties and reactivity within the group.

What does group 18 elements have in common?

all have 8 electrons in the valence shell

How many valence electrons do atoms have in groups 1 and 2?

Atoms in groups 1 and 2 have 1 and 2 valence electrons, respectively. Group 1 elements have 1 electron in their outermost shell, while group 2 elements have 2 electrons in their outermost shell.

What gives elements in a family or group similar properties?

number of electrons in valence (last) shell

What sub level are the valence electrons in group 2?

The valence electrons in group 2 elements are found in the s sublevel. These elements are known as alkaline earth metals and have 2 valence electrons, which occupy the s sublevel of their outermost electron shell.

The elements within a group have a similar number of?

The elements within a group have a similar number of valence electrons. This results in comparable chemical properties and reactivity within the group.

What is the general valence shell configuration for the elements in group 7A?

The general valence shell configuration for elements in group 7A is ns2np5, where n represents the principal quantum number of the valence shell. This configuration results in these elements having 7 valence electrons in their outermost shell.

What elements of a group have the same number of?

Valence electrons (electrons in the outer shell)

The elements in group 7A have one valence electron true or false?

A valence electron, or valence electrons, are found in all of the elements. A valence electron is an electron located on the out most shell of an element (the valence shell). Most elements will have more than one valence electron. Oxygen, or O, has six valence electrons because its outer shell consists of six electrons.

What is the number of electrons needed for stability in the groups of the periodic table?

They r noble gases which have stable valance shell and grotp no. 18

What does group 18 elements have in common?

all have 8 electrons in the valence shell

How many valence electrons do atoms have in groups 1 and 2?

Atoms in groups 1 and 2 have 1 and 2 valence electrons, respectively. Group 1 elements have 1 electron in their outermost shell, while group 2 elements have 2 electrons in their outermost shell.

What are the valence electron of an atom?

The valence electrons are found on the valence shell, the outermost shell of an atom. By using the periodic table and the group numbers, one can find the number of valence electrons for elements in groups (vertical columns) 1-2 and 13-18. For the 1st 2 groups (1 and 2), the group number tells the number of valence electrons for elements which belong in that group Elements in the 1st group have 1 valence electron and elements in the 2nd group have 2 valence electrons. For groups 13-18, refer to the tens' value (the teen value that is not the "1" in these cases). Elements in group 13 have 3 valence electrons, elements in group 14 have 4 and so on to the the final group, 18, where electrons have a full octet 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.

What are the elements that have the same number of valence electrons?

The elements that have the same number of valence electrons are located in a group.The group number from the Periodic Table relates to the number of electrons in the valence shell.For example, elements in group 1 (H, Na, Li, K, Rb, Cs, Fr) all have 1 valence electrons and elements in group 7 (Cl, F, I, Br) have 7 valence electrons in its outer shell.

How valence electrons are mg?

Magnesium (Mg) has 2 valence electrons because it is in group 2 of the periodic table. Group 2 elements have 2 electrons in their outermost shell.

Elements in a group or family have?

the same number of valence electrons (which is the same number of electrons in the atom's outermost shell)
