The ions of Noble gases, <em>group VIII</em> elements have a full octet configuration on their outermost shell and as such are highly stable.
The periodic table is a systematic arrangement of elements in order of their atomic numbers into a set of 8 columns each called groups and a set of 7 rows each called a period.
Elements are arranged in different groups according to the number of Valence electrons they have.
- For instance, elements in the group I of the periodic table are highly electropositive and as such are highly reactive.
The same is evident in group 7 elements are highly electronegative and have high electron affinity and as such are unstable and reactive.
- However, Noble gases, <em>group VIII</em> elements have a full octet configuration on their outermost shell and as such are highly stable.
Consequently, the <em>Noble gases ion</em> has a stable Valence electron configuration.

Answer: apple falling
Explanation: apple is at rest until a force (gravity) acts upon it
A pi bond... hope this helps!!!!!
No. on the left side you will notice there is one Ca, and 2 oxygen. therefore on the right side there must be 1 Ca, and 2 oxygen. The correct answer would be Ca + O2 -> CaO2
Answer: The atomic mass of these two isotopes is 40.03 amu. The average mass is closer to actual amu of 58.69 for nickel as its percentage abundance is more.
Explanation:
Mass of isotope 1 = 63.93
% abundance of isotope 1 = 0.93% =
Mass of isotope 2 = 57.93
% abundance of isotope 2 = (68.08)% =
Formula used for average atomic mass of an element :
Therefore, the average atomic mass of nickel is, 40.03 amu. The average mass is closer to actual amu of 58.69 for nickel as its percentage abundance is more.
