Sodium is a metal element. There are 11 electrons in a single atom.
there is no such element
Sodium is a metal atomic element. So it has no molecules (or whatsoever) in it. It is build up (like all elements) with a nucleus in the center and electrons 'rotating' in shells around it. The numbers and measures of those shells and the electrons therein differ from element to element. There are about 100 elements.
I guess Sodium.
Because atoms can be isotopes or ions, protons are the only stable identifier for an element (Sodium can have more or less than normal number of electrons or neutrons and still be sodium). Sodium has 11 protons.
For an neutral element that has the same number of electrons and protons, the element with 11 electrons is Na, sodium.
As the elemental metal sodium has 11 (eleven) electrons; the same number as the protons, and the atomic no.(Z). However, sodium will readily lose one(1) electron to form the sodium cation (Na^(+)) . When it is the sodium cation it has 11 protons, but only 10 electrons.
The element with 5 fewer electrons than sodium is not a gaseous element!
Sodium
A neutral atom of sodium has 11.
sodium
Assuming that you're talking about one sodium atom and that it's not charged,the number of electrons will have to be 11.Source:http://www.chemicalelements.com/elements/na.html
Elements in Sodium's Group (Group 1 - Alkali Metals) will have the same amount of electrons in their outer shell (i.e. 1 electron in the outer shell).
Sodium is a metal element. There are 11 electrons in a single atom.
If the element has a full valence shell, such as the noble gases, then it is unreactive. It the element is missing few valence electrons of has few valence electrons, then the element is very reactive, such as the sodium.
Each element has a different number of electrons. All atoms of that element have the same number of electrons. The number of electrons is the same as the number of protons.
there is no such element
