Which one of the following elements is located in period 2 and Group 13 of the periodic table?
boron group element, any of the six chemical elements constituting Group 13 (IIIa) of the periodic table. The elements are boron (B), aluminum (Al), gallium (Ga), indium (In), thallium (Tl), and nihonium (Nh).
What elements are found in period 2?
The second period contains the elements lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon. In a quantum mechanical description of atomic structure, this period corresponds to the filling of the second (n = 2) shell, more specifically its 2s and 2p subshells.
Which element belongs to period 2 and group?
For example, an element belong to period 2 and group 2 will have the electronic configuration as . This means that atomic number of this element is 4 and it is beryllium. And, it has 2 valence electrons.
Which of the following elements is found in Group 2 and Period 3?
Magnesium. Magnesium (symbol Mg) is an alkaline earth metal and has common oxidation number +2.
What is the Valency of Group 2 and group 13 elements?
ii) Group 13 elements has valency 3. The compound formed is: Formula of the halides of group 13 is MX3, where M is the group 13 element and X is halogen. iii) Group 2 elements has valency 2 and valency of group 16 elements is 2.
Which element in period 2 has zero Valency?
Valency of First 30 Elements
| Element | Atomic Number | Valency |
|---|---|---|
| Valency of Hydrogen | 1 | 1 |
| Valency of Helium | 2 | 0 |
| Valency of Lithium | 3 | 1 |
| Valency of Beryllium | 4 | 2 |
Which element is in period 2 and has 2 valence electrons?
Where is period 2 on the periodic table?
The horizontal rows of the periodic table are called periods. Period 2, or the second period, refers to the second row from the top of the periodic table.
Which element is in Group 2 IIa and Period 7?
Strontium is a shiny, relatively soft metal. The name of the element is derived from Strontian, a town in Scotland where the mineral strontianite was discovered, from which strontium was first isolated.
What are the physical properties of group 13?
Physical Properties of Group 13 Elements . • Indium has a smaller nuclear radius than Thallium . This is due to the lanthanide compression. • As we move down to the element in the group, the +1 oxidation state turns out to be more stable than +3 states. This is mainly due to the inert pair effect.
What are group 13 metals called?
Group 13 is sometimes referred to as the boron group, named for the first element in the family. These elements are–not surprisingly–located in column 13 of the periodic table. This group includes boron, aluminum, gallium , indium , thallium , and ununtrium (B, Al, Ga, In, Tl, and Uut , respectively).
What are the properties of group 13?
Chemical Properties of Group 13 Elements . Dissociation of the group 13 elements requires a lot of energy. This is because the compounds formed by the Group 13 elements with oxygen are inert thermodynamically. Boron acts as a non-metal chemically. However, the rest of the elements show metallic properties.
