What special names are given to the group you group vii and group viii elements?
group 7 - halogens group 8 - noble gases
What does group 18 elements have in common?
all have 8 electrons in the valence shell
How does the numbers of electrons change across a period of elements?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
What group is the noble gas in?
Group-18 belongs to noble gases. The elements of this group are stable.
Which elements are stable and in the noble gases group?
all the group 8 elements are stable, and are noble gases,. eg Ar, Ne, Kr, Xe, Rn, not sure about Helium though.
How many valence electrons does group 8 have?
Elements in group 8 all have 8 valence electrons, this is why these elements are in group 8, they are called noble gases, some examples are Argon, Xenon,
How many valence electrons can an atom have?
That depends on the element in question. Atoms can have anywhere from 1 to 8 valence electrons. For the main group elements, Groups 1,2,13-18, the number of valence electrons are the number in the one's place in their group number, as follows: Group 1 Elements: 1 valence electron Group 2 Elements: 2 valence electrons Group 13 Elements: 3 valence electrons Group 14 Elements: 4 valence electrons Group 15 Elements: 5 valence electrons Group 16 Elements: 6 valence electrons Group 17 Elements: 7 valence electrons Group 18 Elements: 8 valence electrons The transition metals, Groups 3 - 12, are more complicated because they are adding d electrons, some of which behave like valence electrons, and many transition metals can have different numbers of valence electrons. For example manganese can have anywhere from 2 to 7 valence electrons.
Are the group 8 elements intert?
The naturally-occurring group 8 elements (helium, neon, argon, and kyrpton) are not completely inert, but they are more nearly so than any other group.
What group of elements on the periodic chart are unreactive?
group 8, the noble gasses.
What is different about the group 18 elements?
Group 19 elements have 8 valence electrons (obey octet rule) and are hence stable.
What is method of calculating a valency of an element?
The valency of first four main group elements is equal to their group numbers but elements from Group 5 to 8 have two valencies one equal to group number and second is obtained by subtracting group number from 8.
What are the chemical properties of group 8 elements?
They don't have one. Group 8 is noble gasses.
How many elements are there in the third period of the periodic table?
There are 8 elements in the third period of periodic table. The elements belong to group-1,2,13,14,15,16,17 and 18
What is the name given to the elements in group 8?
=NOBLE GASES=
What type of elements have valence electrons?
Elements in every group of the periodic table has some number of valence electrons. The exception is, when it comes to group 18, the number of valence electrons might be considered as either 0 or 8.
What special names are given to the group you group vii and group viii elements?
group 7 - halogens group 8 - noble gases
What are the elements in group 8 called on the periodic table?
Halogens these are the salt forming elements which are highly reactive
