The noble gas electron configuration for Uranium (IV) ion (U^4+) is [Xe] 4f^14 5d^10. This means that the electrons from the noble gas Xenon are included, along with 14 electrons in the 4f orbital and 10 electrons in the 5d orbital for a total of 24 electrons.
CrO2this is the incorrect formula. For Chromium II oxide the formula is actually CrO without the 2. The reason for this is simple. the II after chromium indicates that it has a charge of +2, and the oxygen, we know is in group 16, has a charge of -2. The formula CrO2 is actually the formula for chromium IV oxide>
Lead (IV) ion is found in the compound lead(IV) oxide, which has the chemical formula PbO2.
Balance the oxidation states on the atoms in the molecule. An oxide always contains oxygen in -2 oxidation state , in ionic compounds this is O2-. As the chromium is Cr(IV) in +4 oxidation state, ( shown as an ion Cr4+ ) you can balance the states or charges which ever way to get CrO2 (which you can write as Cr4+ (O2-)2 )
lead IV chloride
The tin IV ion has 50 protons and 48 electrons. Tin has an atomic number of 50, so it normally has 50 electrons. However, since it is in the +4 oxidation state, it loses 4 electrons during ionization, leaving it with 50 protons and 46 electrons. The charge of +4 means it has 4 more protons than electrons, making the total number of protons and electrons in the tin IV ion 50 and 48, respectively.

The plumbic ion is Pb^4+, and its formula is Pb(IV). This ion is formed when lead (Pb) loses four electrons to achieve a full outer shell of electrons.
This is the chromate anion. It is written CrO42- . It is tetrahedral in shape (like methane). It gives a yellow colour to salts that contain it such as K2CrO4.
CrO2this is the incorrect formula. For Chromium II oxide the formula is actually CrO without the 2. The reason for this is simple. the II after chromium indicates that it has a charge of +2, and the oxygen, we know is in group 16, has a charge of -2. The formula CrO2 is actually the formula for chromium IV oxide>
A Stannic ion is the ion of Tin(IV). Its formula is Sn4+ . Here tin is in its highest oxidation state of +4. The other ion is Stannous(Sn2+).
The correct formula for the ionic compound formed between chromium and chloride is CrCl3. This is because chromium has a 3+ charge and chloride has a 1- charge, so it takes three chloride ions to balance the charge of one chromium ion.
The formula for lead(IV) ion is Pb4+ and for nitrite ion is NO2-.
The symbol for the tin IV ion is Sn4+.
Magnese(IV) Ion
The symbol of lead IV ion is Pb^4+.
lead (IV) ion is Pb4+ ion. Note that Pb4+ is never found as an ion- the (IV) is an oxidation number or oxidation state.
