A sodium ion, Na+, contains the same number of electrons as?
If you look to the periodic table, you will see that Na has an atomic number of 11. That is equal to the number of electrons in elemental Na. Ionized sodium (Na+) got the positive charge by losing one electron, so it has only 10 electrons. Therefore, Na+ has the same number of electrons as the element with the atomic number of 10, which is Ne. Therefore, the answer is d.
Electron configuration of sodium ion?
Sodium??? Sodium has 1 valence electron. Since Na has a very low 1st ionization energy and a high 2nd ionization energy, then it's obvious that sodium only forms an ion with a +1 charge. Can you deduce anything from the yellow color about ionic charge? No ======== Follow up ========= The electron configuration of the ion is the electron configuration of the neutral atom, minus the number of electrons lost to form the positive ion. Na -- [Ne] 3s1 Na+ -- [Ne] Most metals, except for the left-most three columns of the periodic table, can for several different ions. For the representative elements (the "A" columns), electrons will be lost from the orbitals with the highest principal quantum number starting with the p-sublevel, and then the s-sublevel. Transition metals can form ions by first losing electrons from the s-sublevel and then the d-sublevel. The bottom line is that the electrons at the highest energy levels will be lost first. Then we're back to this statement: The electron configuration of the ion is the electron configuration of the neutral atom, minus the number of electrons lost to form the positive ion.
Sodim ha the atomic number 11. how many electrons are in a sodium ion,which has the symbol na+?
Sodium atom has 11 electrons The Na+ ion has a + charge because the atom has lost 1 electron Therefore number of electrons = 10
If sodium has 11 protons, how many electrons will it have when it is electrically neutral?
11 neutral state means protons and electrons are equal when it is positively charged it has more protons then electrons when it is negatively charged it has more electrons then protons So Na- would have 12 electrons and Na+ would have 10 electrons
How many electrons are present in a sodium ion?
The element sodium has 11 electrons (found based on atomic number). A very general rule of the amount of electrons per energy level is 2n^2 so we can conclude that the first two levels are filled since the first electron energy level has space for 2 electrons, and the second has 8 ,leaving space for one lone electron on the third level. When forming ions elements generally try to become more stable and attempt to achieve a filled outer energy level. In this case Sodium will lose one valance electron since it's the easiest way to obtain a filled outer energy level. So a sodium ion will have 10 electrons
What is the atomic number of sodium?
Sodium is a chemical element with symbol Na and atomic number of sodium is 11.Atomic mass: 22.989769 u ± 2 × 10^-8 uMolar mass: 22.9898 g/molElectron configuration: [Ne] 3s1Melting point: 97.79 °CDefinition of atomic number = the atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of an atom. It is identical to the charge number of the nucleus it is called number of atomic .
How many protons and electrons are in sodium ion?
11 protons 10 electrons
How many electrons are in the outer shell of a sodium ion?
The atom's rings are 2,8,1. Sodium is very reactive and willingly gives up its one electron. The answer is not b. There WAS one electron for the atom, but we are talkng about the ion not the atom. c was never a consideration. So now we come to a and d. The question is so poorly worded, that you cannot separate the two. I would say it is 8 because that is what is currently there. They are present. I hesitate to eliminate a however because what is not there is sometimes as good an answer as what is. Since the ion is an ion there is nothing in the third level, so I would pick d. But the question is actually very poor.
Sodium has a mass number of 23 and atomic number of 11. what is the number of neutrons and electrons in sodium?
Atomic no. Is the no. Of protons. Protons are positive, for the atom to be neutral, the no. Of electrons shud be equal to the no. Of protons. Therefore, Atomic no. Can be the no. Of electrons, as well.Mass no is the no. Of neutrons plus the no. Of Protons in the nucleus.Massno= no. Of neutrons + Atomic no. (No of protons =atomic no)23=no of neutron + 11No of neutrons =23–11 =12No of protons=11No of electrons=11
