What is Group 5A on the periodic table?
Group 5A (or VA) of the periodic table are the pnictogens: the nonmetals nitrogen (N), and phosphorus (P), the metalloids arsenic (As) and antimony (Sb), and the metal bismuth (Bi).
How many electrons does group 5A have?
5 valence electrons
Properties of the Group 5A Elements With the exception of nitrogen, all of these elements are solids at room temperature. They all have 5 valence electrons, which are the outermost electrons, farthest away from the center of the atom.
What element in Group 5A is more electronegative?
The valence electron configuration of the group 5A elements is ns2np3. Compounds of these elements exhibit a maximum oxidation state of +5, in which all five valence electrons are shared with a more electronegative element: PF5 is an example.
What is the oxidation number for Group 5A?
The most common oxidation numbers for Group 5A elements are 3, 5, and 3. Nitrogen has oxidation numbers from 3 to 5 in a variety of stable compounds.
What is the correct valence electron configuration for the group 5A elements?
ns2np3
The Group 5A elements have the valence shell electron configuration: ns2np3. This group contains two nonmetals (nitrogen and phosphorus), two metalloids (arsenic and antimony), and a metal (Bi).
What group number is oxygen?

How many valence electrons does an element in group 5A have?
As you know, an element’s valence electrons are simply the electrons located on the outermost energy level, i.e. on the highest occupied energy level. Therefore, you can say that an element located in group 5A has 5 electrons on its highest occupied energy level.
What is the valence electron configuration for the element in Period 4 group 5A?
Which is the largest atom in group 5A?
For your sequence, nitrogen, phosphorus, and arsenic, arsenic, the lowest Group member, will have the least ionization energy, and nitrogen will have the largest.
What is general electronic configuration of 5A group elements?
The Group 5A elements have the valence shell electron configuration: ns2np3. This group contains two nonmetals (nitrogen and phosphorus), two metalloids (arsenic and antimony), and a metal (Bi).
What do group 5 elements have in common?
All the elements of the group are reactive metals with a high melting points (1910 °C, 2477 °C, 3017 °C). The reactivity is not always obvious due to the rapid formation of a stable oxide layer, which prevents further reactions, similarly to trends in Group 3 or Group 4.
What is electronic configuration of oxygen?
[He] 2s² 2p⁴Oxygen / Electron configuration
What is the configuration number of oxygen?
Looking at the periodic table, you can see that Oxygen has 8 electrons. Based on the order of fill above, these 8 electrons would fill in the following order 1s, 2s and then 2p. So Oxygen’s electron configuration would be O 1s22s22p4.
Which group on the periodic table is an atom with 5 valence electrons?
The elements of group 15 (column) VA of the periodic table all have electron configurations of s2p3 , giving them five valence electrons. These elements include Nitrogen (N), Phosphorus (P), Arsenic (As), Antimony (Sb) and Bismuth (Bi).
What is the largest element in group 5A?
Bismuth
Bismuth is the only metal in the group and it is the heaviest element that contains stable (non-radioactive) isotopes. Elements of Group 5A overwhelmingly form covalent compounds.
Which is the smallest atom in group 5A?
So in group five way elements nitrogen will be having the smallest atomic radius when compared to the other elements.
What is the valence electron configuration for the element in period 4 group 5A?
What is general electronic configuration of oxygen family?
elements the general electronic configuration is ns2np4. Six electrons are present in the valence shell. For example the valence shell electronic configuration for oxygen is 2s22p4.
What is the oxygen electron configuration?
Oxygen electron configuration is 1s 2 2s 2 2p 4. The electron configuration of oxygen shows that the period of oxygen is 2 and oxygen is an p-block element. Oxygen electron configuration with an orbital diagram is the main topic of this article. The eighth element in the periodic table is oxygen.
What are the oxidation states of Group 5A elements?
Sometimes group 5A elements lose electrons and form cations, or an atom with a positive charge. Depending on the group 5A element, there can be many oxidation states other than -3 including: +5, +3, +2, and +1.
Why do all elements in Group 5A have 5 valence electrons?
They all have 5 valence electrons, which are the outermost electrons, farthest away from the center of the atom. These valence electrons help determine who the element can bond with, or attach to, as well as its properties. All of the elements in group 5A become more metallic as you go down the group.
