What is more reactive sodium or magnesium?

Sodium and magnesium both elements are in the 3rd period. But in the outermost energy level sodium has one electron but magnesium has 2 electrons. Therefore,attraction between the nucleus and electrons in magnesium higher than that of sodium. Therefore,sodium is more reactive than magnesium.

Why Na is more reactive than Na+ or MG?

A reactive metal has the ability to easily lose an electron and acquire a positive charge. Sodium easily loses electrons and acquires a positive charge. Sodium easily lose electrons than magnesium and get oxidized to easily.

Is magnesium most reactive?

In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom.
…
The reactivity series.
Element Reaction with dilute acids
Calcium Very quickly
Magnesium Quickly
Zinc More slowly
Iron More slowly than zinc

Which is more reactive than magnesium?

Calcium is more reactive than magnesium because the calcium atom is larger than the magnesium atom.

Is magnesium more reactive than potassium?

Therefore, sodium is less reactive with water than is potassium, likewise with the alkaline metals; calcium is more reactive than magnesium. … – So, out of given metals, Potassium is the most reactive metal. Therefore, potassium is the most reactive metal among the given options.

Is magnesium more reactive than aluminum?

Aluminium is more reactive than Magnesium.

Why is magnesium the most reactive?

Why is magnesium more reactive? Magnesium atoms typically lose two electrons to form chemical compounds. A reactive complex has finally been made in which magnesium keeps all of its electrons, and which can be thought of as a soluble form of the metal.

Which is the most reactive metal in the reactivity series?

Reaction with Water and Acids:

Sodium is a most reactive metal. It produces hydrogen and metal hydroxide when it reacts with cold water. Iron which is present in the middle of the table of the reactive series when reacted with sulfuric acid produces hydrogen and metal salt namely iron sulphate.

Is magnesium reactive or nonreactive?

Halogens: When reacted with a halogen, magnesium is very reactive. An example will be with chloride. When reacted with chloride, the product is magnesium(II) chloride. Acids: When reacted with acids, magnesium dissolves and forms solutions that have both the Mg(II) ion and hydrogen gas.

Is magnesium more reactive than hydrogen?

This shows magnesium is more reactive than zinc and both metals are more reactive than hydrogen. … The next four metals (magnesium through chromium) are active metals that will react with hot water or steam to form their oxides and hydrogen gas.

Why is sodium so reactive?

Sodium (Na) is an alkali metal; it is shiny and soft with a single electron in its outermost shell. Alkali metals are highly reactive because they readily lose their outermost electron. Sodium combines with water in an explosive reaction.

Is magnesium or calcium more reactive?

Three points should be kept in mind, however. The alkaline-earth metals tend to lose two electrons to form M 2+ ions (Be2+, Mg2+, Ca2+, and so on). These metals are less reactive than the neighboring alkali metal. … Magnesium is more active than beryllium; calcium is more active than magnesium; and so on.

What is more reactive magnesium or copper?

Magnesium is more reactive than copper. … The magnesium displaces the copper, and the products are copper and a solution of magnesium sulfate.

Why is magnesium more reactive than copper GCSE?

Magnesium ribbon placed into copper sulfate solution will result in the formation of a magnesium sulfate solution and the depositing of copper metal. The magnesium displaces the copper as it is a more reactive metal.

Which is the highest reactive element?

Cesium is second from the bottom of this group, has 6 shells of electrons, and it matches the features of a reactive atom, making it the most reactive element.

Why are larger atoms more reactive?

The larger an atom is, the more reactive it will be. … This makes it easier for the valence electrons to leave the atom and form an ionic bond or to interact with another atom to form a covalent bond. If electrons can leave more easily, then the atom is more likely to react.

What makes an element more 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. … Alkali metals are highly reactive because they readily lose the single electron in their outermost shell.

Is lithium more reactive than sodium?

Reactivity means how reactive something is. All the group 1 metals are reactive, but they get more reactive as you go down the group, so potassium is more reactive than sodium, which is more reactive than lithium. … Give two reasons why lithium is less reactive than sodium.

Why are smaller atoms more reactive?

The smaller the atomic radius, the more influence the nucleus has on reactivity. … The nucleus of smaller atoms is more exposed and thus exhibits a stronger pull. Therefore, the smaller the atomic radius, the more reactive the halogen atom, making fluorine the most reactive element in Group 17.

Are metals more reactive than nonmetals?

Since the ionization energy decreases going down a group (or increases going up a group), the increased ability for metals lower in a group to lose electrons makes them more reactive. … Nonmetals tend to gain electrons in chemical reactions and have a high attraction for electrons within a compound.
