I think its answer choice A because it would better to talk to their parents first and not take matters into your own hands.
Answer:
The 3rd option is correct
Explanation:
The element in group 13 and period 3 is aluminium which has the electron configuration
or [Ne] 3s^2 3p^1
The ball and stick model of C subscript 2 H subscript 4 is described as Option C: Each C has 2 H's connected to it each by 1 black.
This means the same as the 3D structure image of ethylene (C2H4) and means 2 C's connected by 2 black lines.
line.
The structure of ethylene is made up of 2 carbon atoms and 4 hydrogen atoms.
The carbon atoms are located at the middle position and the hydrogen atom surrounding the carbon atoms with two hydrogen atoms connected to each carbon atom. The two black lines connecting the carbons are the double bonds.

Valence electrons in a covalent bond are shared among the bonded atoms.
Answer:
electronegativity of bonded atoms and shape.
Explanation:
if the shape of molecule is symmetric it will non polar. The polar molecules are trigonal in shape.
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion and compound is polar.
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive and compound will polar.
For example:
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive.
