Which side of the periodic table is least reactive?

Answer and Explanation: The noble gas group is the group of elements that are the least reactive. The noble gases are the last column on the right side of the periodic

Likewise, people ask, which side of the periodic table is most reactive?

left

Additionally, which group is least reactive on the periodic table? Noble Gases

In this manner, how do you know which element is least reactive?

Explanation: The reactivity of an element can be determined by looking at the electron configuration of the element. 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.

Which atomic number is least reactive?

Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds.

What is the 2nd most reactive metal?

You will find the alkaline earth metals right next door in Group II. This is the second most reactive family of elements in the periodic table.

What is the least reactive element in Group 2?

alkaline Earth metal

Metal in group 2 of the periodic table that has two valence electrons and is very reactive but less so than an alkali metal.

What metals are most reactive?

The most reactive metal is francium. However, the most reactive metal in the reactivity series is Potassium. You can learn to memorize the reactivity series in the video below: As you can see from the below reactivity series, the most reactive metal are Potassium, Sodium, Calcium.

What is the most reactive element in Group 1?

The most reactive element in the group 1 of periodic table is Caesium and Francium is not considered as it is radioactive.

Which element reacts most vigorously with water?

alkali metals

What makes an element reactive?

The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Halogens are highly reactive because they readily gain an electron to fill their outermost shell.

How can you tell which element is more reactive?

The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive. Lithium, sodium, and potassium all react with water, for example.

What is the least reactive element?

The most reactive metal that has a stable isotope is cesium, which is located directly above francium on the periodic table. The least reactive elements are the noble gases. Within this group, helium is the least reactive element, forming no stable compounds.

Is iodine more reactive than chlorine?

Explain why chlorine is more reactive than iodine. Reactivity of these halogens correspond to its ability to gain an electron. Cl can gain an electron more easily than iodine - Cl more reactive. This is because Cl is higher up Group 7 than iodine (Cl: 2,8,7 electron configuration).

Is potassium more reactive than sodium?

As potassium is larger than sodium, potassium's valence electron is at a greater distance from the attractive nucleus and is so removed more easily than sodium's valence electron. As it is removed more easily, it requires less energy, and can be said to be more reactive.

What is the least reactive element in Period 4?

Copper is the least reactive element. In the periodic table, reactivity decreases from left to right and increases from top to bottom. Furthermore, potassium is an alkali metal, calcium is an alkaline earth metal, and copper is a transition metal.

What is the least reactive element in Group 7?

Reactions with water

The reactivity of the alkali metals increases down the group. Lithium is the least reactive and potassium is the most reactive of the three.

Which element is the most reactive out of the list below?

Reactivity of Group 1 Elements

The reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least reactive alkali metal and francium (Fr) is the most reactive.

Which element is more reactive lithium or beryllium?

Identify which element is more reactive: lithium, Li, or beryllium, Be. Lithium is more reactive as it has only one electron in its valance shell. Beryllium has 2 valance electrons. Lithium is more reactive as it is easier to lose oneelectron than losing two electrons.

Which group on the periodic table is the most stable?

noble gases
