Why is nitrate negatively charged?
The nitrogen atom loses 5 electrons to the three oxygen atoms.
But these three oxygen atoms want 6 electrons.
And so when, for example, sodium forms the compound sodium nitrate, NaNO3, the single outer-shell sodium electron transfers over to the NO3, making it a nitrate ion, giving it a -1 charge..
What is the charge of H?
+1A hydrogen atom is made up of a nucleus with charge +1, and a single electron. Therefore, the only positively charged ion possible has charge +1.

What is the charge of zinc?
+2Zn always forms a 2+ ion. In fact, all of the elements in that group (Group 12) forms 2+ ions. This is because after losing the 4s electrons Zn still has a a closed n=3 shell, which is a very stable electron configuration common oxidation state is +2.
How many lone pairs are present in nitrogen?
A single lone pair can be found with atoms in the nitrogen group such as nitrogen in ammonia, two lone pairs can be found with atoms in the chalcogen group such as oxygen in water and the halogens can carry three lone pairs such as in hydrogen chloride.
How many lone pairs are on the circled nitrogen?
one lone pairExplanation: The nitrogen will have three bonds and one lone pair.
What is the charge of a nitrogen ion?
A nitrogen atom must gain three electrons to have the same number of electrons as an atom of the following noble gas, neon. Thus, a nitrogen atom will form an anion with three more electrons than protons and a charge of 3−. The symbol for the ion is N3−, and it is called a nitride ion.
Is nitrogen a cation?
Nitrogen is neither a cation nor an anion because it is an atom and atoms are electrically neutral. Nitrogen has five valence electrons and it needs…
Can nitrogen have 2 lone pairs?
The Lewis dot structures of the individual, non-metal atoms give a good indication of the bonding possibilities for the atoms. Carbon tends to form 4 bonds and have no lone pairs. Nitrogen tends to form three bonds and have on e lone pair. Oxygen tends to form two bonds and have two lone pairs.
Which is more stable H+ or H?
Answer. H is more stable because H+ has charge..and its is replaceable…
Is H+ an acid?
An acid is a solution with more H+ ions than OH- ions. An acid is any compound that yields hydrogen ions (H+) or hydronium ions (H3O+) when dissolved in water. Hydronium ions – are the combination of H+ ions and H2O molecules.
What is charge of carbonate?
The carbonate ion consists of one carbon atom and three oxygen atoms and carries an overall charge of 2−.
Why can nitrogen only form 3 bonds?
Nitrogen has five valence electrons, so it needs three more valence electrons to complete its octet. A nitrogen atom can fill its octet by sharing three electrons with another nitrogen atom, forming three covalent bonds, a so-called triple bond. The triple bond formation of nitrogen is shown in the following figure.
