Genetic variation can be caused by mutation
Answer: 10HSiCl3 + 15H2O → H10Si10O15 + 30HCl
Explanation:
E and B
Explanation:
The last option violates Aufbau's principle.
Aufbau's principle states that "the sublevels with lower energies are filled up before those with higher energies."
This implies that orbitals are not filled based on numerical order but on their energy levels.
The order is as follows;
1s 2s 2p 3s 3p 4s 3d e.t.c
In B, the 3s was not filled before jumping to 3p
In E, 3p was not filled before jumping to 3d and 3d was not even the next orbital.

Because the Earth<span> is a sphere, the surface gets much more intense sunlight, hence heat, at the equator than at the poles.</span>
The distribution of heat around the globe, and through the year, coupled with the physical properties of air, produce a distinctive pattern of climatic zones.
It is actually something standardized more so than theoretical, however in terms of atoms in general the electrons are based on the amount of electronic shells that an atom has and the amount of electrons that atom can accommodate. In the case of sodium, it has three shells with 2 electrons on the first shell which is the maximum, 8 on the second shell which is also the max and 1 on their final shell
So simply put an ATOM of Sodium (Na) has 23 electrons because it has 23 protons which is a fact
