B) linear
C) tetrahedral
D) trigonal pyramidal
An element's chemical properties are determined by the number ofelectrons .
The number of electrons determine chemical properties of an atom as they are present in equal number outside the nucleus as that of protons .Protons contribute to the mass of an atom and give an identity to an atom .
As protons are positively charged there is a need to balance this positive charge and it is balanced by an equal number of electrons .As the valence electrons are the electrons which take part in chemicalreactions the element's chemical properties are determined by the number of electrons.
The number of neutrons has a negligible effect on the chemical nature of elements as they are neutral and have no charge.Indirectly, it's the electronic configuration of an element which determines the chemical properties of any element.

An Atom is best described as a positive nucleus surrounded by a cloud of negative charges, with the nucleus containing protons and neutrons, and an outer cloud of electrons.
The phrase that best describes an atom is (B) a positive nucleus surrounded by a cloud of negative charges. An atom consists of two regions: the nucleus, which is centrally located and contains protons and neutrons which are positively charged and neutral respectively; and the electron cloud, which is made up of electrons, that are negatively charged, in constant motion around the nucleus. Therefore, we can visualize the atom as a positive nucleus surrounded by a cloud of negative charges.

Answer:
Cyclohexane, water, mercury.
Explanation:
One result of Archimedes' principle is that, in a container, the substance with the highest density will be in the bottom of the container and the substance with the lowest density, will be in the top of the container.
In the test tube with mercury, water and cyclohexane. In the top you will have cyclohexane (Least dense), in the middle will be the water and in the bottom will be mercury.
From the top to the bottom:
Cyclohexane, water, mercury.
