What Is The Least Reactive Group On The Periodic Table

Neon has an atomic number of 10.

Which of the following groups of elements is ranked from least reactive to most. This is what is meant by periodicity or periodic table trends. The least reactive elements are those who have a full outermost valence shell i e. Nitrogen makes up 78 of earth s atomsphere white oxygen makes up around 21.

Only 18 elements on the periodic table are considered nonmetals. Neon is the least reactive element on the periodic table. They have 8 electrons in the outer shell so elements such as helium neon radon or the transition elements. As a noble gas neon is colorless and odorless with extremely low reactivity in its natural state.

Which of the following atoms is least able to attract electrons. The noble gas group is the group of elements that are the least reactive. 3 nonmetals o s se 1 metalloid te and 1 metal po. Noble gasses group 8 are the least reactive elements in the periodic table because they have a full valence shell.

The least reactive elements are those who have a full outermost valence shell ie they have 8 electrons in the outer shell so elements such as helium neon radon or the transition elements. Element xx is very reactive.

Neon is considered the most noble of the gases as it has the lowest reactivity in a group of elements with low reactivity. The noble gases are the last column on the right side of the periodic table. The right most column group 8 or the noble gases is the least reactive. The oxygen group is group 6a on the periodic table.

The noble gas group is the group of elements that are the least reactive. There are multiple ways of grouping the elements but they are commonly divided into metals semimetals metalloids and nonmetals. Since they have 8 electrons in the outer shell and because the maximum number of electrons in the outer shell is 8 electrons then the element doesn t need any extra electrons nor does it need to get rid of it. 6 valence electrons.
