Answer:
Option B. +3 and +6
Explanation:
<em>Zeff</em> = <em>z - s</em>
where <em>z</em> is the atomic number, <em>s</em> is the number of shielding(non-valence) electrons
For Boron, electronic configuration is 1s²2s³.
z = 5, s = 2
Zeff = 5 - 2 = +3
For Oxygen, electronic configuration is 1s²2s²2p⁴
z = 8, s = 2
Zeff = 8 - 2 = +6
The sets of characteristics describe what we know about
the inner planets is that have rocky
surfaces, no rings, and few or no moons. The answer is letter C. Also, they are
smaller in sizes compared to the outer planets. The rest of the choices are
characteristics of the outer planets.
Answer:
Atomic neutron mass electron number
Explanation:
The answer is Velocity and potential energy. Kinetic energy is the total energy of a system or an object in motion and requires movement.
It is achievable for the same enzyme to catalyze reverse reactions for the reason that the direction of a reversible reaction is determined by the concentrations of reactants and products. In pulmonary circulation, the low CO2 concentration supports the making of CO2 and H2O.
