How many electrons does the element B have in its outer shell?
Boron has 3 electrons in the outer shell and 2 electrons in the inner.
How many element do the elements belonging two group IIIA have in there outermost shell?
Elements in group IIIA, also known as group 13, have 3 electrons in their outermost shell. This is because they are located in the third column of the periodic table, which determines the number of valence electrons an element has based on its group number.
How many electrons dose boron have in its outer shell?
Boron has three electrons in its outer shell
How many electrons does a aluminum atom lose to form an ion?
an aluminum atom will lose the 3 electrons on its outer shell 2 for an aluminum ion.
Which period contains the element silicon?
The element Silicon (Si) is in the third Period on the Periodic Table. It is also the second element in Group 14(4) - The Carbon Family. It has 14 electrons in 3 shells, with 4 electrons in the outer shell.
How many electrons does the element B have in its outer shell?
Boron has 3 electrons in the outer shell and 2 electrons in the inner.
Number of electrons in the outer orbit of an atom of lithium?
A neutral atom of lithium has an electron configuration of 2,1. This means it has 1 electron in its outer shell.
What a period 3 element with 4 electrons in its outer shell?
n
What causes electrons to flow through a conductor?
There are 1 to 3 electrons in outer orbit of a conductor witch the element wants to give away in order to have inner orbit complete at the cost of getting positive charge when forced by the electric voltage.If outer orbit have 4 electrons like carbon,silicon or germanium, it acts as a semiconductor. And if outer orbit have more than 5 electrons, it will resist electron flow.
What neutral atom is isoelectronic with nitrogen?
Nitrogen (N) has 7 electrons in total. 2 in its first orbit and 5 in its second orbit (only has two orbits because it is in the second period of the periodic table). For a full, outer shell/orbit (8 electrons), it needs 3 more electrons.5+3 = 8Nitrogen has a charge of 3- which means it needs 3more electrons. If you add how many electrons it has gainedto the total number of electrons Nitrogen has (7) then you will find the element it is isoelectronic with.7+3 = 10Now find the element with 10 electrons (# of electrons = # of protons & # of protons = the atomic number of an element).Neon (Ne) on the periodic table has an atomic number of 10 so therefore, Ne/Neon is the isoelectronic atom with Nitrogen.
What compound has less than 8 electrons?
Lithium is an example of an element that has less than 8 electrons. It has 3 electrons in its outer shell.
Why nitrogen is trivalent elements?
Nitrogen is a trivalent element because it has five electrons in its outer shell, and it needs three more electrons to achieve a stable octet configuration. By sharing three electrons through covalent bonding, nitrogen can reach a stable electron configuration, resulting in a valency of three.
How many electrons does boron have in its outer shell?
There are three electrons in boron's outer energy level.
What is the number of valence electrons in the outer shell of each element of group 3?
3: For periodic columns 1 through 3, the number of valence electrons is the same as the number of the periodic column.
The number of electrons in the outermost shell of an element is 5 what is its valency and why?
Its valency is 3 i.e. 8-5.The element is a non metal since it has 5 electrons in the outermost shell.Hence, it is very difficult for the element to loose 5 electrons and would be easier togain 3 electrons .Hence, the element gains 3 electrons and thus we consider its valencyto be 8- no. of valence electrons.
What element has 3 energy levels and 8 neutrons in its outer energy level?
The element with 3 energy levels and 8 neutrons in its outer energy level is oxygen, with the symbol O. Oxygen has 8 protons and 8 neutrons in its nucleus, with 2 electrons in its inner energy level and 6 electrons in its outer energy level.
Why nitrogen is trivalent?
Because it contain 3 unpaired electrons in its outer most orbit which incolve in bond formation
