01 What did Ernest Rutherford's gold foil experiment demonstrate about an atom?
Each atom is composed of electrons and positive material,
The mass of the atom is evenly spread throughout the atom.
O Neutrons are located in the center of the atom.
O Positive charge occupies a very small volume in the atom.

The correct answer is -  Positive charge occupies a very small volume in the atom.

Explanation:

Ernest Rutherford's experiments exhibited the presence of the nuclear core: a small region with the greater part of the mass of the atom and the positive charge.  

Rutherford's gold foil analyze gave three conclusions:  

- the particle is generally vacant space  

- in it is a little, thick core  or dense nucleus

- the core is positively charged.

i'm not sure

explanation:

i'll try whatever you got

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
