Which of these elements is the most chemically reactive?
The most reactive element is fluorine, the first element in the halogen group. The most reactive metal is francium, the last alkali metal (and most expensive element).
Which element is chemically very reactive?
The most reactive elementary group is alkali metals (situated far apart from intermediate metals and noble gases). 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 the most reactive element.
Which of these elements is the most chemically reactive quizlet?
Francium is the most reactive. Their outer shell has 1 electron. They are also called ‘the alkali metals’. These are known as the ‘noble gases’.
What is the 2nd most reactive metal?
Alkaline Earth Metals
The alkaline earth metals are the second most reactive family of elements. Beryllium, magnesium, calcium, strontium, barium and radium are all shiny, and silvery-white.
Which metal is more reactive?
The ionization enthalpy of potassium is minimum. It is the most electropositive and most reactive metal. It reacts with air as well as water vigorously.
Which element in each pair is more reactive?
Answer: (1) O is more reactive.
What elements have the same properties?
Elements in the same group of the periodic table have similar chemical properties. Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals.
Which element is the most reactive Brainly?
Among all the elements on periodic table, Halogen (17th group) elements are most reactive ’cause of high electronegativity. & among all of them, “Fluorine” is most reactive.
Which metal is the most reactive Why?
Caesium
Caesium, the most reactive metal in the periodic table, reacts extremely violently – hence why it can’t be demonstrated in a classroom! This can be compared to other common metals, such as iron and copper, which produce no reaction when dropped into water.
How can you tell which metal is more reactive?
The primary difference between metals is the ease with which they undergo chemical reactions. The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive.
Which set of elements are most reactive?
Fluorine is one of halogen gas that is known as highly reactive. It should be the most reactive element in the periodic table. All halogen gas is reactive because they need 1 more electron to complete their set of valence electron. Nonreactive element would be the noble gas which has a full set valence of electron.
Which is the most reactive element in halogen gas?
All halogen gas is reactive because they need 1 more electron to complete their set of valence electron. Nonreactive element would be the noble gas which has a full set valence of electron. Rate!

What are noble gases on the periodic table?
The noble gases, also known as inert gases or aerogens, are chemical elements that make up Group 18 (VIIa) of the periodic table. Under standard conditions, these elements have similar properties; they are tasteless, odorless, colorless, and nonflammable. These elements are helium, neon, argon, krypton, xenon, radon, and oganesson.
