2,8,3 because Aluminium has the Atomic Number 13
Answer: Mixture
Explanation:To form brass, copper and zinc combine but do not chemically bond. Brass is a(n)
Answer:
Detail is given below
Explanation:
Atomic radii trend along group:
As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.
As the size of atom increases the ionization energy from top to bottom also decreases because it becomes easier to remove the electron because of less nuclear attraction and as more electrons are added the outer electrons becomes more shielded and away from nucleus.
In A we can see that there is one positive charge and force of attraction is 2.30×10⁻⁸ N and distance is 0.10 nm
In B we can see that negative charge is further away from nucleus because of greater distance thus force of attraction will be less. 0.58×10⁻⁸ N
In C this distance further increases and force also goes in decreasing 0.26×10⁻⁸ N.
Answer:
uh i think its D All of the above
Explanation:
sorry if its wrong
Answer:
C
Explanation:
Adaption is an animal adapting to be better suited for its enviroment, a bird being able to fly better is an example of that. :)
