How do the number of electrons in the second energy shell of an atom change going across period 2 in the periodic table?
The answer is: A. The number of electrons increases by 1, from left to right.
B is wrong because atoms in period 2 DO have a second energy shell. For C, the number of electrons in the second energy shell is NOT full. For D, it is wrong to state that the number of electrons increases by 1, from right to left.
Answer:
The reason that that elements in the same 'group' have similar chemical properties is because they have the same number of valence electrons. ... Iron when reacting in chemical reactions loses electrons from its 4s orbital instead of its d orbital
Yes. Heating up the solvent gives the molecules more kinetic energy. The more rapid motion means that the solvent molecules collide with the solute with greater frequency and the collisions occur with more force. Both factors increase the rate at which the solute dissolves.
