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.
Answer:
1,000 daughter cells
Explanation:
The meiosis process can form up to 4 daughter cells: 250 x 4 = 1,000 cells.
Answer:
Ions are an atom or group of atoms that either has a positive or negative charge. An ion with a negative charge is called an anion and one with a positive charge is a cation.
Hope this helps :)
Lycopodium is a family of fern-allies .
They are mostly a flowerless plants with widely branched, with little and simple,
needle-like like leaves that
cover the branches thickly and stem while Equisetum usually called horsetail, snake
grass because it more like a tail of a horse and its the only living genus in Equisetaceae,
a family of vascular
plants that reproduce by spores rather than
seeds.
