Cesium
– The most ACTIVE metal on EARTH!
Which element is the most active metal?
The most active metals in the activity series are
lithium
, sodium, rubidium, potassium, cesium, calcium, strontium and barium. These elements belong to groups IA and IIA of the periodic table.
What element in the third period is most reactive?
the most reactive non metal in third period elements is
chlorine
. It is also the most reactive element after fluorine.
Which element is most active?
- The periodic table is composed of 18 groups and 7 periods. …
- In groups, it increases from left to right whereas, in periods, it increases from bottom to top.
Which metal is only liquid?
Mercury
is the only liquid metal found at normal temperatures.
What is the least reactive element in period 3?
Silicon
. Silicon (symbol Si) is a group 14 metalloid. It is less reactive than its chemical analog carbon, the nonmetal directly above it in the periodic table, but more reactive than germanium, the metalloid directly below it in the table.
What is the most active nonmetal in period 3?
Chlorine
. The most active nonmetal in any period is second to last (halogens), right before the noble gases.
Which is the least reactive element in the row Na to Ar?
Noble gases
are nonreactive, nonmetallic elements in group 18 of the periodic table. Noble gases are the least reactive of all elements. That’s because they have eight valence electrons, which fill their outer energy level.
Which element is most likely to bend without breaking?
Cobalt
is the element which is most likely to bend without breaking.
What is the only nonmetal in Group 1?
Hydrogen
, with its single electron, also lives in Group 1, but the gas is considered a nonmetal.
Which is active metal?
Active Metals is a collective name for metals that react strongly or quickly with other substances. … Examples of active metals are
Lithium, Sodium, Potassium, Rubidium, and Cesium
, which are also known as the “Alkali” metals.
Which is the lightest liquid metal?
Mercury (Hg)
is the lightest liquid metal. Its density is 13.6 times more than that of the water. At room temperature, mercury is a liquid.
Which metal can easily cut with knife?
Sodium
is silver white color metal with malleable and ductile property. It is the metal that can easily be cut with a knife.
Which metal is stored in kerosene?
Sodium
and Potassium are highly reactive metals and react vigorously with the oxygen, carbon dioxide and moisture present in the air such that it may even cause a fire. To prevent this explosive reaction, Sodium is kept immersed in kerosene because Sodium doesn’t react with kerosene.
Are the least reactive metals the cheapest?
As you can see, least-reactive metals are
not necessarily the cheapest
. … In the reactivity series, copper, gold, and silver are at the bottom and hence are least reactive. One of the reasons why non reactive metals are good conductors is that they are good at staying as metals.
Where is Period 3 on the periodic table?
Period 3, or the third period, refers to
the third row from the top of the periodic table
.
