Explanation:
The noble gases are found in group 18 of the periodic table with a complete valence electron shell. The elements of group 18 are chemically stable because their valence shells are filled.
However, Xenon differs from other noble elements because of its size and large number of electrons. The electrons in the outer shell are not tightly bound with the nucleus and thus, are somewhat free to part in reactions, this why xenon has so many compounds
Answer:
Electronegativity increases across the period on a periodic table.
Explanation:
Electronegativity is the ability of an atom to attract electron to itself.
All elements on the periodic table combines in order to have a complete octet i.e they all want to be like the noble gases, group 0 elements.
This is what drives most atom to combine chemically. By so doing, they either lose or gain electrons.
Cl belongs to the 7th group on the periodic table. It is the second element in this halogen group. Most halogens are notable for their high electronegativity. They have 7 electrons in their outermost shell and would require just an electron to complete their octet.
This makes them highly reactive and combine readily with other elements.
The halogens have a strong attraction for valence electrons. The higher the electronegativity value, the stronger the attraction an atom has for valence electrons.
Most metals like Al and Na are electropositive and readily donates or lose electrons so as to have a complete octet.
Answer:
The study of the human body as a machine for the performance of work has its foundations in three major areas of study—namely, mechanics, anatomy, and physiology; more specifically, biomechanics, musculoskeletal anatomy, and neuromuscular physiology. Explanation:
