its letter d ..................................
Answer:
This is because their atoms have the same number of electrons in the highest occupied energy level. Li lithium and K potassium both belong to first group (alkali metals) and thus have similar chemical properties.
Explanation:
Answer:
In FeO iron atom exist as Fe+ cation but in Fe2O3 iron atom exist as Fe3+ cation.
Explanation:
Feo=Fe+ + O-
Fe2O3 =2Fe3+ + 3O2-
The difference in the charge of iron cation deeply affect the compound formulas because in FeO the Fe cation has 1 unit positive charge where in Fe2O3 the Fe cation has 3 units positive charge.
That"s why these two chemical compounds made up of similar atoms differ in their chemical formulas.
Answer:
Explanation:
Lead (Pb) has 2 positive oxidation states, +4 and +2.
Sulfur (S) has 3 oxidation states: +6, +4, and -2. Since lead creates a positive ion, sulfur must be a negative ion to balance the charges.
There are 2 atoms of sulfur, each with a charge of -2. Therefore, their overall charge is -4, because 2* -2= -4.
A compound has a net charge of 0. To achieve this, lead must have a charge of +4 to balance out the -4 charge of sulfur.
Lead has a +4 ionic charge in PbS₂
