Explanation:The tetrahedral shape is formed by the electrons repulsing one another, which forms the tetrahedron—the shape in which all the electrons are as far away from one another as possible.
Examples include methane (CH4) and ammonium(NH4+).
Methane has a central carbon atom ringed by four hydrogens, which form the "spokes" of the tetrahedral molecule.
Tetrahedral molecules are nonpolar if the four surrounding atoms are the same, in the cases of methane and ammonium, and have a bond angle of 109.5˚.
However, tetrahedral molecules can also be polar if they are like chloroform (CHCl3). The central atom has four electron domains, but they are differently sized.
Can you re-word better? i'm having a hard time reading this.
Answer:
<span>When a newly found cells enters into interphase and begins conducting metabolic functions,it is in G1 phase.
Reason:
Inter-phase is composed of:
1. G1 phase:
In this phase normal metabolism and growth of newly formed cell occurs.
2. S phase:
In this phase DNA replication occurs.
3. G2 phase:
In this phase cell prepare themselves for division.</span>
