So, just by looking at the periodic table, you can predict lithium will be less reactive than sodium, and francium will be more reactive than cesium and all of the other elements listed above it in the element group.
What happens to the atomic radius as you move down a column?
As you move down a column or group of the periodic table, the size of the atomic radius increases. For the metals, this means the outermost electrons becomes farther away from the positively-charged nucleus. These electrons are easier to remove, so the atoms readily form chemical bonds.
What is the measure of how likely a chemical species is to participate in a chemical reaction to form chemical bonds?
Reactivity is a measure of how likely a chemical species is to participate in a chemical reaction to form chemical bonds. An element that is highly electronegative, such as fluorine, has an extremely high attraction for bonding electrons.

Additionally, the most reactive non-metal element on the periodic table is fluorine, which has the symbol F and atomic number 9.
How accurate is Cesium?
Cesium has numerous applications, one of which is its use in atomic clocks. The first accurate cesium clock was built in 1955 by British physicist Louis Essen. Since then cesium clocks have improved significantly, and are now considered the most accurate form of time keeping, with an error of just 2 or 3 parts in 10 14, which is equivalent to 2 nanoseconds per day or 1 second every 1.4 million years. Furthermore, the latest cesium clocks are even more accurate, with an error of 1 part in 10 15, which is equivalent to 1 second every 20 million years. Cesium clocks are now used to regulate the timing of the internet and mobile phone networks. In 2018, it was proposed that the definition of the second should be based on the numerical value frequency of Cesium-133.

The alkali metals are the family of elements that contain the most reactive elements. These metals include lithium, sodium, potassium, rubidium, cesium, and francium
Did you know that some metals are so reactive that they explode on contact with water? Certain metals like potassium, sodium, lithium, rubidium, and more, are so reactive, that they oxidize (or tarnish) instantly when exposed to air. Some of these metals can produce explosions when dropped in water.
What determines reactivity?
Reactivity is a measure of how likely a chemical species is to participate in a chemical reaction to form chemical bonds. For example, an element like fluorine, who is highly electronegative, has an extremely high attraction for bonding electrons.
What happens with alkali metals?
The alkali metals are the family of elements that contain the most reactive elements. These metals include lithium, sodium, potassium, rubidium, cesium, and francium. Moving down the column, metals become more reactive because the nucleus gains more electrons and protons.
Reactive metals
As we mentioned before, the reactivity series of metals is a chart listing metals by their reactivity.
How do you know which non metal is more reactive?
The most reactive nonmetal is fluorine, F. The trend in reactivity in the nonmetals is the opposite of the trend in the metals. In the nonmetals, reactivity increases as you move up a group, and to the left. In the metals, reactivity increases down a group and to the right.
Why are halogens the most reactive nonmetal?
All of the halogens are nonmetals. Halogens are reactive because they want to obtain that last electron to fill their outer level. Fluorine is the smallest atom of the halogen elements. It also has the strongest ability to attract electrons from other elements, making it the most reactive of the halogens.
Why are nonmetals reactive?
Some nonmetals are very reactive, whereas others are not reactive at all. It depends on the number of electrons in their outer energy level. Reactive nonmetals tend to gain electrons. This explains why they cannot conduct electricity, which is a flow of electrons.
Why are halogens so reactive?
Halogens are highly reactive, and they can be harmful or lethal to biological organisms in sufficient quantities. This reactivity is due to high electronegativity and high effective nuclear charge. Halogens can gain an electron by reacting with atoms of other elements. Fluorine is one of the most reactive elements.
Where are halogens found?
All of the halogens can be found in the Earth's crust. Fluorine and chlorine are fairly abundant with iodine and bromine being somewhat rare. Astatine is extremely rare and is considered one of the rarest naturally occurring elements on Earth.
Which group is least reactive?
Group 18 elements are nonmetals called noble gases (see Figure below). They are all colorless, odorless gases. Their outer energy level is also full, so they are the least reactive elements.
Who discovered halogens?
Davy's name for the element prevailed. However, in 1826, the Swedish chemist Baron Jöns Jacob Berzelius proposed the term "halogen" for the elements fluorine, chlorine, and iodine, which produce a sea-salt-like substance when they form a compound with an alkaline metal.
Which metal is the most reactive?
The most reactive metals are the alkali metals namely Lithium, Sodium , Potassium. Rubidium and Cesium. They belong to family IA and they readily form ions with +1 charge by losing an electron in their outermost shell. The most reactive non-metals are those that belong to the halogen group or the VIIA group.
Which element is the most reactive non-metal?
F - Fluorine. It is the most reactivate non-metal due to high electron affinity. Infact it is the most reactive non radioactive element in the periodic table because it belongs to the group 17 , Period 2 , p-block or we can say Halogen Family. It is a diatomic gas at STP (Standard Temperature and Pressure).
What is a reactive pan?

You can use these pans for all kinds of foods, though you may not get the heat conductivity of copper or cast iron. 3.5K views.
What is unstable at another level?
The radioactive metals are unstable at another level, that is not dependent on reacting with other elements. When metals are in contact with air, water, acids etc the tendency for a reaction to take place is largely determined by how stable the theoretical result of a reaction. Continue Reading.
Why is aluminum lusterous?
In the case of Aluminum. A metal is lusterous because it has free electrons, whose properties create the “mirroring” effect. As electromagnetic radiation impinges on the surface of a metal, the oscillating electro-magnetic field interacts with the electrons, creating a reflected electromagnetic field.
Which metals are difficult to break apart?
Some of those oxide compounds are very stable, and difficult to break apart. Titanium, aluminum and magnesium are very active metals that form oxides that are nearly inert, and it takes a lot of energy to break them apart to form the metallic elements that we’re familiar with.
When metals are in contact with air, water, acids, etc., the tendency for a reaction to take
When metals are in contact with air, water, acids etc the tendency for a reaction to take place is largely determined by how stable the theoretical result of a reaction would be . Things tend to react if the result will be more stable overall, than the starting point is.
