Directions: Respond to each statement on the lines provided. 5. Determine how an electron dot diagram provides information on the number of
bonds an atom of a certain element can form.
6. Write an example of two types of atoms that are likely candidates to form a chemical
bond.
7. Draw an electron dot diagram for fluorine (F), which has seven valence electrons.
8. Explain why some elements, such as the noble gases, are stable and do not react
with other atoms, but the atoms of other elements are unstable and form chemical
bonds easily

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
