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.
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.
Define the periodic table of elements?
The periodic table of elements arranges elements in order of Atomic Number, Reactivity and Relative Atomic Mass. The columns are called 'Groups' the rows called Periods. It mostly contains metals on the left side and non-metals on the right. There are basically 8 groups of elements that as you go down the group the element becomes more reactive.
Is 52563744 divisible by 24?
Sol: 24 = 3 x 8, where 3 and 8 are co-primes. The sum of the digits in the given number is 36, which is divisible by 3. So, the given number is divisible by 3. The number formed by the last 3 digits of the given number is 744, which is divisible by 8. So, the given number is divisible by 8. Thus, the given number is divisible by both 3 and 8, where 3 and 8 are co-primes. So, it is divisible by 3 x 8, i.e., 24.
What group and period does iron belong to?
Period 4 Group 8
What special names are given to the group you group vii and group viii elements?
group 7 - halogens group 8 - noble gases
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 is a group of elements in the periodic table?
A group is a column in the periodic table of elements.
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 are elements in a column called?
The elements in the 8 main columns of the Pperiodic Table are called Groups. Groups 1 and 2 are separated from Groups 3 to 8 by a block of elements called the Transition Series and the columns in this series have no specific names.
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.
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 are the chemical properties of group 8 elements?
They don't have one. Group 8 is noble gasses.
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 are the elements in group 8 called on the periodic table?
Halogens these are the salt forming elements which are highly reactive
