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 many valence electrons do atoms have in groups 1 and 2?
group 1...is 1 valence. group 2...is 2 valence.
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?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
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)
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?
group 1...is 1 valence. group 2...is 2 valence.
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 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.
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.
Which atoms have six valence electrons in their valence shell?
The atoms with six valence electrons are the elements of group sixteen. This list includes O, S, Te, Se, and Po. If you would like to answer this yourself, just remember that the last digit of the group number is typically the number of valence electrons that you will have. The exceptions of course are the transitional metals from group 3 to 12 and the lanthanides and actinides like uranium and plutonium. These have 2 valence electrons.
