Caesium is the most reactive metal in the periodic table, so much that working with this metal often ends in explosions!

Nonmetals often share or gain electrons. Tarnishes when freshly cut at room temperature … The most reactive metals on the periodic table are the alkali metals, which have a single valence electron. Caesium, the most reactive metal in the periodic table, reacts extremely violently – hence why it can’t be demonstrated in a classroom! Most reactive: Sodium (Na) Reacts vigorously when heated.

The nonmetals in the periodic table increases as you move to the right and decreases as you go down. Links Metals Revision Questions gcsescience.com The Periodic Table Index Reactivity Series Quiz gcsescience.com In order in your list from the most reactive to the least reactive is Potassium, Sodium, Calcium, Magnesium, Iron, Copper and Zinc. Favorite Answer. The metals in the bottom left corner of the periodic table is the most reactive.

The next reactive series of metals are the alkaline earth metals such as magnesium and calcium that have two valence electrons. In the reactivity series strontium is a radioactive element with highest reactivity amongst the given choices. The common reactivity series of metals in decreasing order of reactivity is: K, Na, Ba, Ca, Mg, Al, Mn, Zn, Fe, Ni, Sn, Pb, H, Cu,Hg, Ag, Au,Pt.

the elements at the left hand side of the periodic table is the most reactive and the elements at the right hand side is the least reactive.

The observations of the reactivity series of metals reacting with water, metals reacting with hydrochloric acid and metal displacement reactions are described and tabulated below. 3 Answers. Fluorine is identified as the most electronegative element in the periodic table, making it the strongest oxidizing agent. List the metallic ions in order of most reactive to least reactive based on the number of times they were involved in spontaneous reactions. Beryllium (Be) is the only alkaline earth metal that does not react with water or steam, even if metal is heated to red heat.

The most reactive is at the top, the least reactive at the bottom. most reactive at top, least reactive at the bottom: Mg2+ Zn2+ Fe2+ Ni2+ Sn2+ Pb2+ Cu2+ Ag+.

The most reactive metals, such as sodium, will react with cold water to produce hydrogen … According to HyperPhysics, alkali metals include potassium, sodium and cesium. Magnesium is very reactive. This can be compared to other common metals, such as iron and copper, which produce no reaction when dropped into water.

Lithium, sodium, and potassium all react with water, for example. Ag+.

Source(s): simple reactivity series.

Relevance.

It is the most reactive non-metal.

Whereas Technetium is little less reactive as compared to strontium. Yellow/orange flame and white solid formed.

Mg2+ Cu2+ Zn2+ Fe2+ Pb2+ Ni2+ Sn2+ Answer Save. These revision notes on reactivity series of metals experiment observations should prove useful for the new AQA, Edexcel and OCR GCSE (9–1) chemistry science courses. 1 See answer Answer Expert Verified 0. taskmasters. The alkaline earth metals (Be, Mg, Ca, Sr, Ba, and Ra) are the second most reactive metals in the periodic table, and, like the Group 1 metals, have increasing reactivity in the higher periods.

In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom.
