Which is the correct formula for titanium (iii) oxide?

a. ti2o3
b. tio
c. ti3o2
d. ti2o4

The correct answer is Option A.

Explanation:

Titanium is the 22nd element of the periodic table with electronic configuration of

In the naming of the compound, the oxidation state of this element is given +3.

Oxygen is the 8th element of the periodic table with electronic configuration

This element will easily gain 2 electrons and shows an oxidation state of -2.  

By criss-cross method, the oxidation state of titanium and oxygen gets reversed and they form the coefficients of the compound.

The compound formed by the combination of Titanium(III) and oxygen is having chemical name of Titanium (III) oxide.

Thus, the correct answer is Option A.

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
