What is the name given to the elements in group 8?
=NOBLE GASES=
Which chemical family is composed of elements that have full valence shells?
Valence shells mean that the outermost orbits of electrons are full. Recall that from the inside out, the number of electrons for a shell to be full are: 2, 8, 8, 8, etc... So, Helium, He (2) has a filled shell. Neon (10) has a filled inner shell (2) and a filled outer shell (8): 2 + 8 = 10. Argon (18) has a filled inner shell (2), another filled shell (8), and a valent shell (8): 2 + 8 + 8 = 18. The family is composed of the non-reative Noble Gases.
How readily astatine would be to form a salt compared to other elements in Group 17?
Astatine wouldn't form salt as readily as other elements in Group 17. Astatine is a radioactive metalloid. Other elements in Group 17 are nonmetals.
What is group 18 on the periodic table?
In Periodic table , Group 18 corresponds to Nobel gas group. They are six elements in this group. Helium , Neon , Argon , Krypton , Xenon , Radon constitute these group. They are chemically inert elements and having stable configuration.
What element is in group 4 and period 2 on the periodic table?
Group 4 elements on the periodic table contain no period 2 elements whatsoever.
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,
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=
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.
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
What element has the configuration 2 8?
Neon - one of the stable and unreactive elements of group 8.
How many elements on the periodic table of elements?
In the Periodic table of Elements There are 118 Elements 96 are metals The rest are non-metals Group 7= Halogens Group 8/0= Noble gases Going down group 1 and 2, elements become more reactive
