Does hydrogen belong to Group 17?
Does hydrogen belong to Group 17?
The reason why the hydrogen can be placed in both group 1 and group 17 is that it resembles Alkali metals in some of its properties like it can easily form cations so, it can be placed in Group 1 of periodic table but it also resembles Halogens in its properties like it forms which is true property of halogen that is …
Why is hydrogen at the top of Group 17?
Because hydrogen is a nonmetal and forms H- (hydride anions), it is sometimes placed above the halogens in the periodic table. Hydrogen also forms H2 dihydrogen like halogens. However, hydrogen is very different from the halogens. Hydrogen has a much smaller electron affinity than the halogens.
What is the name of the group 17 elements excluding hydrogen?
halogens
The halogens are the elements in Group 17 (formerly Group VII or VIIa) of the periodic table. They are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At) and the as yet undiscovered ununseptium (Uus).
Is hydrogen a Group 1?
Hydrogen (H, Z=1). Although hydrogen is placed at the top of Group 1A in most versions of the periodic table, it is very different from the other members of the alkali metal group.
What is the place of hydrogen in periodic table?
So if you glance at the periodic table, you will see hydrogen is the first element in the table. It is the smallest element on the table. It has atomic number one, which means it has only one electron orbiting it its shell. In fact, Hydrogen has only one shell.
What do you think should hydrogen be placed in group 17 of halogens or Group 1 of alkali metals in the modern periodic table?
Hydrogen’s atomic number is 1,hence there is only 1 electron in outermost shell. So to be stable Hydrogen loses its electron and makes 1 positive charge. Therefore, instead keeping Hydrogen in group of halogens it should be in group 1st that is alkali metals group.
Where is hydrogen in the periodic table?
Why the position of hydrogen can be placed either in group 1 or Group 17 in the first period?
Hydrogen can be placed in both group 1 and group 17 because its electronic configuration is similar to both the groups. However, like group 17 elements, it requires only electron to complete its valence shell, thus it can also gain an electron to achieve a noble gas configuration.
What is the collective name for the Group 17 elements?
The halogens are located on the left of the noble gases on the periodic table. These five toxic, non-metallic elements make up Group 17 of the periodic table and consist of: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
What are the following groups known as Group 17?
(ii) Group 17- halogens- Fluorine. Chlorine.
What is the name of Group 18 on the periodic table?
noble gas
noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).
What is group 17 on the periodic table of elements?
Group 17 of the periodic table of the elements consists of the so-called halogen elements fluorine, chlorine, bromine, iodine, astatine with general electronic configuration ns2np5.
What group does hydrogen belong to on the periodic table?
Hydrogen in Periodic table Hydrogen element is in group 1 and period 1 of the Periodic table. Hydrogen is placed along with the alkali metals group as it has the similar outer electron configuration as that of the group 1 elements (i.e ns 1 ).
What is the group number of hydhydrogen?
Hydrogen can be placed in group number 1 or (but not normally) in group number 17 because it has some properties similar to both groups. On one hand , it exhibits the property of alkali metals by losing one electron to get a positive charge ( H –> H+ + e-).
What are the elements in the group VIIA?
Fluorine, Chlorine, Bromine, Iodine, Astatine, and Tennessine constitute group VIIA (17 group elements) of the long form of the periodic table. The elements of the group are known as halogens (halos = salt, gen = product). These are all p block elements with the differentiating electron entering the P -orbital.
