The elements within a group have a similar number of?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
What does group 18 elements have in common?
all have 8 electrons in the valence shell
How do you determine the number of valence electrons if you know the group no of elements?
valence electrons are electrons at the outermost shell as we all know, group in PE can be determined by looking at the valence electron thus if it is in group 1..then the valence electron is 1
What gives elements in a family or group similar properties?
number of electrons in valence (last) shell
How many valence electrons do the elements is group two have?
Group II elements (also called alkaline earth metals), have two valence electrons. To fill their outer shell, they therefore become ions with two positive charges, such as magnesium: Mg -> 2e- + Mg2+
The elements within a group have a similar number of?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
What elements of a group have the same number of?
Valence electrons (electrons in the outer shell)
How many electrons will the elements have in the second group have on the periodic table?
There are 2 valence electrons (electrons in the outer shell) of group 2 elements in the ground (un-ionised or standard) state. This causes them to form +2 ions.
What does group 18 elements have in common?
all have 8 electrons in the valence shell
What is the general valence shell configuration for the elements in group 7A?
Valence electron configuration in group 7A (halogens): ns2, np5 in which n=2, 3, 4, 5, ... etc. Starting with fluorine, F, electron configuration: (1s2), 2s2 2p5 (non valence electrons in () brackets)
Group 1a elements have how many electrons in their valence shells?
All these have one electron in their valence 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 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.
How do you determine the number of valence electrons if you know the group no of elements?
valence electrons are electrons at the outermost shell as we all know, group in PE can be determined by looking at the valence electron thus if it is in group 1..then the valence electron is 1
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.
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.
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)
