Because of Its High Reactivity Which Element

Metal chloride hydrogen. In the outermost shell it has 7 seven electrons which means that it needs just one more electron to attain an octet configuration in that shell.

Comparing Halogen Reactivity Trends With Those Of The Alkali Metals Halogens Become Less Reactive Down The Chemistry Classroom High School Chemistry Chemistry

The equation for reacting a metal with acid is.

. A sulfur b lithium c argon d gold. The reactivity of metals is because of their incomplete outer orbitals or due to their electronic configuration. Sodium is a most reactive metal.

Reactive elements release great quantities of energy when they combine with other elements. The thing that makes fluorine so reactive is its electronegativity. Some highly reactive elements are fluorine sodium potassium lithium and oxygen.

The most reactive metal is francium the last alkali metal and most expensive element. Because it isnt below carbon in the reactivity series. Fluorine is an extremely reactive pale yellow-green gas.

Due to its high reactivity this element cant be found in its free state. Which element is more reactive. Acid metal -- salt hydrogen.

A substance that has a high reactivity. Metal sulphuric acid --. Halogens are highly reactive because they readily gain an electron to fill their outermost shell.

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. They readily lose their loosely-bound outer electron to form ions and compounds. Chlorine has an atomic number of 17 and a configuration of 2 8 7.

However francium is an unstable radioactive element only found in trace amounts. So the better it is at stealing electrons the more reactive it will be. Add a liquid with a density less than 21 gmL until the glass begins to float.

Which type s of glass could it be. The elements in this group are not found freely in nature only in the minutest traces primarily due to their high reactivity. The most reactive element is fluorine the first element in the halogen group.

Terms in this set 28 Potassium OR Sodium. They become more reactive as you go down the table. Up to 24 cash back This happens because as you go down a group it is easier for electrons to be taken or given away resulting in high Chemical Reactivity.

Therefore since fluorine has a higher electronegatvity than chlorine fluorine is more reactive. Answer the following14Part C Which element is most likely to react with oxygen. Reactivity is an elements ability to gain an electron.

Oxygen is less reactive than Fluorine Beryllium is less reactive than Lithium This is in general because larger numbers of electrons need to be exchanged. It produces hydrogen and metal hydroxide when it reacts with cold water. 2NaS 2H2Ol 2NaOHaq H2g 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.

When going across a period reactivity decreases when going from the outside to the inside. These elements are called the alkali metals. Their outer shell has 1 electron.

Because of its high reactivity which element is normally found only combined with other atoms. ADVERTISEMENT MORE FROM REFERENCECOM. Add a liquid with a density greater than 21 gmL until the glass begins to float.

You could also say the alkaline earth metals. Metal hydrochloric acid --. Therefore its can react quickly with any nearby nucleoph.

Sodium is so high on the reactivity series that the only effective way of extracting it is by electrolysis. Francium is the most reactive. The list of metals in the order of how quickly they react.

Chemistry questions and answers. Because of its high reactivity which element is normally obtained by the electrolysis of its fused salts. The most reactive elementary group is alkali metals situated far apart from intermediate metals and noble gases.

They are also called the alkali metals. The farther down a group you go generally the higher the reactivity so francium should be the most reactive metal. Alkali metals are highly reactive because they readily lose the single electron in their outermost.

Metal nitric acid--. Niccherip5 and 5 more users found this answer helpful. And you go from left to right on the periodic table elements have more electrons in their valence shells they have to get rid off which requires an element to have high energies which results into lower Chemical Reactivity.

The most highly reactive elements are halogens which are looking to gain one more electron and alkali metals which are looking to lose the single electron in their outer shells. Some tarnish in air or explode in water. However francium is synthetic and has only been produced in extremely small quantities which decay very rapidly so Im willing to bet that no one has dropped francium into water to test the results.

A piece of glass floats in a liquid with a density of 26 gmL. It reacts violently with nearly everything including metals steel wool and even glass. Record that the density is less than 21 gmL and stop the analysis.

Metals form positively charged ions as they tend to lose electrons. Metals with high atomic numbers tend to be more reactive as their electrons are far from the positively charged nucleus so they can be removed easily.
