What metals are on the electromotive series?
The order of some common metals in the electromotive series, starting with the most easily oxidized, is: lithium, potassium, calcium, sodium, magnesium, aluminum, zinc, chromium, iron, cobalt, nickel, lead, hydrogen, copper, mercury, silver, platinum, and gold.
What is EMF series?
An electromotive force series (EMF series) is a metal’s ranking in respect to inherent reactivity. The metals located at the top of the series are considered the most noble, with the highest level of positive electrochemical potential.
What is the order of electrochemical series?
Arranging redox equilibria in order of their E° values The electrochemical series is built up by arranging various redox equilibria in order of their standard electrode potentials (redox potentials). The most negative E° values are placed at the top of the electrochemical series, and the most positive at the bottom.
What are the types of electrochemical series?
Electrochemical Series
Element | Electrode Reaction (Reduction) | Standard Electrode Reduction potential E0, volt |
---|---|---|
Mn | Mn+++ 2e = Mn | –1.18 |
Zn | Zn2+ +2e–=Zn | –0.7628 |
Cr | Cr3++3 e– = Cr | –0.74 |
Fe | Fe2++ 2e– = Fe | –0.44 |
Which is the non metal in electrochemical series?
Electrochemical series of some non-metals
Red → Ox + e | ε° (Volt) |
---|---|
2I– → I2 + 2e | +0,54 |
2Br– → Br2 + 2e | +1,07 |
2F– → F2 + 2e | +2,87 |
What is the reactivity series of non metal?
Nonmetal activity series is a list in which nonmetals are arranged in the decreasing order of their reactivity. Similar to metals, we can also arrange nonmetals in terms of their reactivity. During displacement reactions, a more active nonmetal displaces a less active nonmetal from a compound.
What is EMF series and write its application?
EMF series is defined as the arrangement of the electrode with the electrode half-reaction in order of decreasing standard potentials.
How are metals arranged in the electrochemical series?
Metals are arranged in the electrochemical series based on the ease with which atoms of metals lose/gain electrons to form positively charged ions. Metals are arranged in the electrochemical series based on the ease with which atoms of metals lose/gain electrons to form positively charged ions.
What is activity series of metals and non metals?
The activity series is a list of elements in decreasing order of their reactivity. Since metals replace other metals, while nonmetals replace other nonmetals, they each have a separate activity series.
What are the reactivity series of metals and non metals?
Reactivity series of metals and nonmetals are the lists, in which we arrange them in the decreasing order of their chemical activity. It is also known as the activity series. The reactivity series helps us to predict the capability of a metal to displace another metal during a displacement reaction.
What is the difference between EMF and galvanic series?

Which of the following metal is more reactive in EMF series?
alkali metal are most reactive metals.
What are the activity series of non metals?
What is non-metal reactivity series?
Non-metals in the reactivity series Here is the reactivity series including carbon and hydrogen: Note that zinc and iron can be displaced from their oxides using carbon but not using hydrogen. However, copper can be extracted using carbon or hydrogen.
What is the reactivity series of non-metal?
Is EMF series and electrochemical series are same?
Electrochemical Series: A series of electrodes or half cells arranged in order of their increasing standard oxidation potentials or in the decreasing order of their standard reduction potentials is called as electromotive force series or electrochemical series. Electrochemical series is also known as e.m.f. series.

Which is the most reactive nonmetal?
Fluorine
Fluorine is the most reactive non-metal because it is the most electronegative of all of the non-metal elements of the periodic table. Due to its strong electro negativity & small size, Fluorine has a strong tendency to accept electrons from other atoms or ions.
What is activity series of metals and non-metals?
Which of the metal is highest in reactivity series?
Down the reactivity increases. Francium is most reactive element in periodic table.
Is plastic is a non-metal?
Is plastic non-metal? For elements, the term metal and non-metals are used. Plastic is not an element but a polymer consisting of various non-metals such as carbon, hydrogen, oxygen, nitrogen and so on. Not all plastic can be deformed, either.
