If a sodium ion has a plus 1 what does that mean about its number of electrons?

An electron is formally assigned a -1 charge. Therefore, if the ion is +1 then that means it has lost an electron- it has 11 normally, so 11-1 = 10 electrons!

What does a valence number of 1 plus mean?
Valence number is the number of chemical bonds that an element can form- these bonds may be covalent (sharing of electrons) or ionic (transfer of electrons). A valence number of 1 means that the element forms just one bond, for example sodium -- forms NaCl - with an ionic bond; hydrogen forms HCl - with a covalent bond.
How many electrons and protons in Na plus?
The cation of sodium has 11 protons and 10 electrons.
Which is larger a sodium atom or sodium ion with a plus 1 charge?
The sodium atom is much bigger than a sodium cation with a plus 1 charge, because the "lost" electron of the ion had a higher principal quantum number than any remaining electron in the ion and therefore was distributed through a larger volume of space than any of the remaining electrons.
What does the symbol Na plus mean?
Sodium
What species has the greatest number of electrons I- or Cu2 plus or Fe3 plus or Au or Hg?
Hg will have 80 electrons.
How many electrons are in a sodium cation Na plus?
The number of electrons is 10.
What information about electrons does the periodic table give?
The atomic number (Z) gives the number of protons in the atom. For a neutral atom, this is equal to the number of electrons. For an ion, plus or minus the number given by the charge. i.e. sodium has atomic number 11, so Na would have 11 electrons and Na+ would have 10 electrons (each electron is -1 remember)

Difference between Na and Na plus?
Na+ will be a sodium atom that has lost an electron. Normally in atoms the amount of protons and electrons are equal, when you see a plus or minus charge on an atom its due to the loss or gain of electrons.

What is the total number of electrons present in an Mg 2 plus cation?
The Mg2 plus cation has 10 electrons.
What does na plus mean?
A monovalent sodium cation.
How the atomic number related to the core electrons?
For a neutral (uncharged) atom, the total number of electrons is equal to the atomic number (number of protons). This would be the sum of the core electrons plus the valence electrons.
What equals to the number of protons plus the number of electrons?
2 * Z
