Technically, the concept of valence electrons applies only to individual atoms, not to molecules or ions such as NH4+. As atoms, each nitrogen atom has five valence electrons and each hydrogen atom has one valence electron, so that the ion could be said to have a total of nine valence electrons.

∙ 14y agoAmmonium is not an atom it is a polyatomic ion. It is made up of 1 nitrogen atom, 3 regular hydrogen atoms, and 1 hydrogen atom that is missing an electron. That makes it's formula NH4-
So to answer you question, an ammonium ion has 8 valence electrons.

∙ 15y agoNH3 =====> 8... Because H is in group 1 so it has 3(1)
and N is in group 5 so 5 valence electrons...
you add 3(1) + 5 = 8 valence electrons... TADA !

N = 5
H2 = 1x2 = 2

Draw the Lewis electron structure for the molucule of ammomonium ion NH4 plus?
The dot structure for ammonium, or NH4 begins with a single N atom in the center. At each cardinal direction, there is one single bonded H atom. The entire structure is bracketed and noted with a + superscript.
What is the valence of an element or radical?
Valency is the charge of an ion or radical which has either lost or gained electrons Note that metals lose electrons easily to become positive ions. This is why most metals are good conductors of electricity. A Radical is a group of atoms usually charged which can keep itself intact and behaves like a unit in a chemical reaction. For example:hydroxide ion (OH-) and ammonium ion (NH4+). When A compound contains more than one such radicals then the formula of this is taken in brackets with their number written on the lower right hand side.
How many atoms does the substance nh4 have?
the ion NH4+ has five atoms (one nitrogen and four hydrogen)
How many bonding and non-bonding electrons does nitrogen have?
In order to have a net charge of zero, nitrogen can have three bonds. it will often have more or less than that number with a charge on the atom. Example: Ammonia (NH3) versus Ammonium (NH4+)
What is the total number of moles of hydrogen in 1 mole of NH4 2HPO4?
8
Why does the ammonium cation nh4 1 have 10 valence electrons?
If it's a -1, then that would be adding an electron.NH = 9 valence electrons (n=5 h=1(4))4the -1 would just add an electron.
How much electrons are there in nh4?
Nitrogen = 7 electronsFour hydrogens = 4 electrons-----------------------------------------add11 electrons in ammonia=================(NH4 +)
What is valency number for NH4?
The valency of Ammonium (NH4) is +1.
What element has two valence electons?
Here at Afuelscience.com we use this method...the number of valence electrons is the number of s and p electrons in the outermost shell (highest n). The number of valence electrons can also be determined by counting across the period, skipping the transition metals, until the element is reached. It is also the group number. If there is more than one atom, the number of valence electrons is the sum of all the atoms in the molecule or polyatomic ion. For ions, add the value of a negative charge and subtract the value of a positive charge. >> Example 1 How many valence electrons are in the following? # N # H2S # CO32- # NH4+ Solution: # Nitrogen is in group 5A. It has five valence electrons. # Hydrogen has one valence electron, and sulfur has six. The total for the molecule is 2(1) + 6 = 8. # Carbon has four valence electrons; oxygen has six; then two for the charge. 4 + 3(6) + 2 = 24. # Nitrogen has five valence electrons; hydrogen has one, minus one for the charge. 5 + 4(1) - 1 = 8.

Are the electrons in a coordinate bond donated by both the bonded atoms?
No - one atom provides both electrons for the covalent bond. eg when ammonia (NH3) forms an ammonium ion, the nitrogen in ammonia provides 2 unbonded valence electrons. These form the covalent bond between the hydrogen ion (H+) and the nitrogen which becomes an ammonium ion - NH4+
What is the molcular geometry of NH4?
The molecular geometry of NH4+ is tetrahedral. This is because NH4+ has four bonding regions (four hydrogen atoms bonding with the central nitrogen atom) and no lone pairs of electrons on the central nitrogen atom.
