Answer:

4 or 3 atoms; leaning towards 4 more

Explanation:

Answer:

3 atoms

Explanation:

The given oxygen and lithium atoms are unable to form a stable compound.

The given atoms to form a stable compound has been oxygen and lithium.

A stable compound has been formed when the transfer of atom has been resulted in the completion of the valence shell of both the electrons.

The oxygen has 6 valence electrons and require to gain 2 electrons to form the stable compound. The Lithium has 3 electrons and has been able to lose 1 electron to form a stable compound.

Since, the formation of stable compound between oxygen and lithium requires transfer of 2 electrons, and there has been availability of 1 electron from Li. Thus, the atoms are unable to form a stable compound.

A shortcoming of Rutherford’s model of the atom is it did not account for the fact that atoms have equal numbers of protons and electrons. Therefore, option C is correct.

Ernest Rutherford, a scientist who was born in New Zealand, developed the Rutherford model to explain an atom. Rutherford oversaw the Geiger-Marsden experiment, which, after Rutherford's analysis in 1911, indicated that J. J. Thomson's plum pudding model of the atom was flawed, in 1909.

The first person to recognize an atom's nucleus was Rutherford. He attacked gold with -particles and discovered that there was positively charged material inside the atom as a result.

It did not explain the distribution of the atom's negatively charged electrons around its positively charged nucleus.

Thus, option C is correct.
