What is the electronic configuration of element having 11 electron?

If it has 11 electrons it must have 11 protons to balance the charge. So the element is Na. But you know it's going to be an isotope of Na since the number of protons and number of neutrons are different. To find out which isotope you have, you must get the mass number which is just the number of protons plus the number of neutrons (remember, they are the only ones that have mass) 11+12= 23
So you have Na-23

∙ 13y agoAn atom with 11 protons suggest that it has 11 electrons.
Thus the electronic configuration is: 2, 8, 1

Why does the sodium ion have at 1 charge?
it is because in order to gain noble gas configuration same as neon it need to lose one electron so when it loses that electron it became electropositive ion having +1 charge on it. second reason for having +1 charge is that when sodium loses an electron it will have 10 electron in total and no of protons are 11 so the total charge on ion became positve
What element is located in the first row of group 1 why is the box for this element separated from the rest of group 1 by a slight space?
Hydrogen. it stands alone because it is made up of one proton one nuetron and one electron. by only having one of each gives this element a nuetral charge.
Do valence electrons affect the reactivity of an element?
atoms are most stable when they have filled the outer shell of electrons which normally holds a max of 8. so if an atom has 1 electron in its outer layer getting rid of it will give him stability, in much the same way having 7 electrons will mean gaining one electron will give it stability. now lets say the two meet, they react with each other and everybody is happy. It is thought than when two elements react, they are trying to acheive a "perfect" electronic configuration (i.e. have a full outer shell). The more electrons needs to lose/gain before acheiving this stability determines its reactivity.
Does fluorine form a cation or a anion?
Fluorine is a neutral atom, though fluoride is an anion. Fluorine does not form cations, or any compound, complex ion, or coordinate complex in which it has a positive oxidation state, unlike the other halogens.
What is an aluminum atom?
An atom is simply the smallest component of an element having the chemical properties of the element. An aluminum atom, is simply that, the smallest part of aluminum having the chemical properties of aluminum.
What element has the electron configuration 4s2 3d7?
First, we need to add up the number of electrons in the configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10. Doing so gives a result of 30. A neutral element having 30 electrons will also have 30 protons. Checking the periodic table, we see that zinc is the element with 30 protons.
Why the metal is very reactive?
Metals , generally, have electronic configuration: with outermost electron having 1,2 or 3. Since, they can easily attain noble gas configuration to attain stability; they readily loose electron.
General electronic configuration of group having low ionisation energy?
The general electron configuration of the group having the lowest ionization energy is [Noble gas configuration]xs1. In this case, x is the principal quantum number of the valance electron. The noble gas configuration may either be written out in full or denoted by the noble gas' atomic symbol in brackets (ie [Ne]).
How can you tell what elements will bond with other elements?
By having a close look on the electronic configuration we can easily tell that which element will combine with the other elements and by which force too.
The arrangement of electrons in an atom is called?
A unit of matter, the smallest unit of an element, having all the characteristics of that element and consisting of a dense, central, positively charged nucleus surrounded by a system of electrons. The entire structure has an approximate diameter of 10 -8 centimeter and characteristically remains undivided in chemical reactions except for limited removal, transfer, or exchange of certain electrons.
Why do metals in Group 1 get more reactive nearer the bottom of the Group?
The reactivity of an element largely depends on its electronic configuration. All the 1st group elements have one electron each in the outer most s-orbital. Their reactivity is due to the loss of this electron and formation of a uni positive ion. The ease with which the element loses the electron dictates its activity. As we go down the group, the distance between the outer most orbital and nucleus increases and hence the ease with which the element loses the electron increases as we go down the group. So naturally the reactivity increases. However in the case of 7th group elements(halogens) the electronic configuration is s2p5. They acquire stability by acquiring another electron. This is called electron affinity. This increases as we go up a group. So we find the more reactive element at the top of the group. We can generalize this like this. The reactivity of an element depends on the ease with which it acquires the nearest iner gas electronic configuration.
What would the electron configuration of atoms of a noble gas be?
(a) The element with electron configuration: 1s2 2s2 2p6 3s2 3p5; (b)A noble gaseswith f electrons; (c) a fifth-period element whose atoms have three unpaired pelectrons; (d) First row transition metals having one 4s electron.

What is the electron configuration called that has 18 electrons in the outer energy level?
Noble gasAn atom's atomic number tells us its number of protons and electrons. Checking the periodic table for the element having an atomic number of 18, we find that it is argon. Argon's electron configuration is 1s2 2s2 2p6 3s2 3p6, which has all of its energy levels filled.
