they generally have 3 valence electrons
The element in group V of the periodic table with 3 electron shells is Phosphorus (P). Group V elements have 5 valence electrons and the number of electron shells corresponds to the period number on the periodic table, so a Group V element with 3 electron shells is in period 3.
Yttrium (Y) is considered a group A element as it belongs to group 3 of the periodic table. The group A elements are also known as the representative elements or main group elements. These elements have their outermost electron configurations organized into groups on the periodic table.
Elements in group three basically have THREE electrons in their outtermost orbitals.However, reactivity increases down the group with Thalium(Tl) being the most reactive as its outtermost electrons are further away from the nucleus.These elements react by losing 3 electrons and therefore they all have a valency of +3.
Elements in the 1st group have 1 valence electron. So they are likely to donate 1 electron to get more stable. potassium, rubidium and cesium are likely to donate 1 electron.
The element belongs to Group 3 of the periodic table. This is because the outermost electron configuration is 3d^(1)4s^(2), where the d orbital has one electron and the ns orbital has two electrons.
Elements in group 1 are called Alkali Metals, after that group 2 elements are called Alkali Earth Metals, group 3-12 elements are called Transition Elements.
The general electron configuration for atoms in Group 5A is ns^2 np^3, where "n" represents the principal energy level. This group includes elements like nitrogen, phosphorus, arsenic, antimony, and bismuth.
All of the elements, apart from the transition metals in the middle, are divided into groups. Group 1 elements have 1 electron in their outer shell, and this is the electron used in bonding. Group 2 have 2 electrons, Group 3 elements have 3, and so on. Group 8 elements have a full outer shell, so they generally don't react.
The element in group V of the periodic table with 3 electron shells is Phosphorus (P). Group V elements have 5 valence electrons and the number of electron shells corresponds to the period number on the periodic table, so a Group V element with 3 electron shells is in period 3.
In the modern periodic table, these elements belong to group 17. These elements have s2 p5 electron configuration. Hence they need one more electron from an electron donor to fulfill its valence shell to obtain noble gas configuration.The elements in the group 7A has 7 electrons in their outermost energy level. They gain 1 electron to get the noble gas configuration. The elements in the group 7A are called halogens.
Yttrium (Y) is considered a group A element as it belongs to group 3 of the periodic table. The group A elements are also known as the representative elements or main group elements. These elements have their outermost electron configurations organized into groups on the periodic table.
An electron first appears in an f orbital in the period 6 and group 3 of the periodic table. This is when the f sublevel starts to fill in elements such as lanthanum (La), which has a electron configuration [Xe] 5d1 6s2.
Group 13 elements, such as Boron and Aluminum, generally lose 3 valence electrons and form compounds with other elements in nature. They are commonly found in minerals and ores in combination with other elements, due to their tendency to form stable compounds through electron loss.
Elements in group three basically have THREE electrons in their outtermost orbitals.However, reactivity increases down the group with Thalium(Tl) being the most reactive as its outtermost electrons are further away from the nucleus.These elements react by losing 3 electrons and therefore they all have a valency of +3.
Elements in the 1st group have 1 valence electron. So they are likely to donate 1 electron to get more stable. potassium, rubidium and cesium are likely to donate 1 electron.
The number of valence electrons in groups 3 through 7 is the same as the group number, and for group 12 the number of valence electrons is 2. For groups 8 through 11, the number of valence electrons must be determined individually from individual electronic configurations.
The oxidation number for the element in group 15 (nitrogen group) is usually -3, as these elements tend to gain 3 electrons to achieve a stable electron configuration.
