What are two most reactive groups in the periodic table?
The alkali metals (Group 1) and the halogens (Group 17) are the most reactive groups in the periodic table. Alkali metals are highly reactive due to their low ionization energies, while halogens are reactive because of their strong tendency to gain an electron to achieve a full outer shell.
What are the two main differences in 1A and 7A elements?
The classification with 1A, 7A etc. is not recommended by IUPAC and is obsolete.The 1A elements are alkali metals, all solids; the 7A elements are the nonmetals (halogens). Halogens can be gaseous, liquids or solids at room temperature.
What are the most reactive nonmetals located on the periodic table?
The most reactive metals are located at the left top of the periodic table. Fluorine is the most reactive non metal. The next two members are oxygen and chlorine.Fluorine, chlorine and bromine are highly reactive. They easily gain electron. They are present in group-17.
What are two properties of halogens?
different Halogens have different properties such as flourine: has an extremely low melting point of the top of my head it's somewhere around -249000 degrees centigrade unlike bromine which has a higher melting point flourine's colour is a green and grey
Which 2 groups are the most reactive on the periodic table?
The alkali metals (Group 1) and the halogens (Group 17) are the two most reactive groups on the periodic table. Alkali metals readily lose their outermost electron, while halogens readily gain an electron to achieve a full outer shell.
The two most reactive groups of elements in the periodic table are the alkali metals and the what?
The two most reactive groups of elements in the periodic table are the alkali metals and the halogens. Halogens are nonmetals located in group 17 of the periodic table and include elements like fluorine, chlorine, and iodine.
Are Halogens the most reactive nonmetal?
It is true that halogens are most reactive non-metals. This is because of two reasons:-They have only seven electron in their outermost shell. Thus, they get stable configuration only on gaining one electron.Also, halogens are the most electronegative elements and have very attracting power for electrons.
What are two most reactive groups in the periodic table?
The alkali metals (Group 1) and the halogens (Group 17) are the most reactive groups in the periodic table. Alkali metals are highly reactive due to their low ionization energies, while halogens are reactive because of their strong tendency to gain an electron to achieve a full outer shell.
Why are the alkali metals and the halogens among the reactive elements an the periodic table?
alkali metals have one valence electron and halogens have 7. since elements always want to have a full outer shell, these two types of elements react easily with each other to form a full outer shell of 8 electrons.
What is an element that is highly reactive gaseous nonmetal?
Chlorine and fluorine, with fluorine more reactive. Some would also include oxygen. (The two remaining halogens are not gaseous at room temperature.)
What is special about the two rows directly below the periodic table?
The special thing about the two rows directly below the periodic table is that they are lanthanoids and actinoids. They are both highly reactive with halogens and chalcogens. Actinoids react more easily, however.
Why Oxygen is react more slowly than halogens?
Oxygen does not react more slowly than all of the halogens, just some of them. Plus, the rate of a reaction depends on its nature, not just whether oxygen or a halogen reacts. when the halogens do react faster, this is because they only need one electron to have a stable configuration, whereas oxygen needs two.
Which element need two more electrons in its outer shell to reach an octet?
Except for hydrogen, these elements are called the halogens. The halogens are highly reactive and easily form both covalent and ionic compounds. Hydrogen is also highly reactive, though it is usually a reducer while halogens are usually oxidizers.
What are the two main differences in 1A and 7A elements?
The classification with 1A, 7A etc. is not recommended by IUPAC and is obsolete.The 1A elements are alkali metals, all solids; the 7A elements are the nonmetals (halogens). Halogens can be gaseous, liquids or solids at room temperature.
What are the most active groups in the periodic table?
The most active groups in the periodic table are Group 1 (alkali metals) and Group 17 (halogens). Alkali metals are highly reactive due to their tendency to lose an electron, while halogens are highly reactive due to their tendency to gain an electron to achieve a full outer shell.
What are the most reactive nonmetals located on the periodic table?
The most reactive metals are located at the left top of the periodic table. Fluorine is the most reactive non metal. The next two members are oxygen and chlorine.Fluorine, chlorine and bromine are highly reactive. They easily gain electron. They are present in group-17.
Is sulphur more reactive than phosphorus?
Sulfur is a fairly reactive non metal. It burns in air to form sulfur dioxide, it reacts with most metals to make ionic sulfides, and with halogens to make covalent compounds. It does not react with water or acids, but does react with hot alkalis.
