An atom has four electrons in its valence shell. what type(s) of covalent bonds is it capable of forming with oxygen? an atom has four electrons in its valence shell. what type(s) of covalent bonds is it capable of forming with oxygen? single bonds only it cannot form covalent bonds with oxygen single and double bonds double bonds only

From the octet rule, an element would only be stable if it has a total of eight electrons in its valence shell. Therefore this atom can still acquire 4 more electrons. Since oxygen has 2 available electrons, hence the atom can either form a single bond or double bond with oxygen.

 

single and double bonds

Yes you are correct use the scientific method

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
