Ionization Energy: DOWN a Group: Ionization energy DECREASES as you go DOWN a Group because the farther the valence electrons are from the nucleus (pulling power of the protons) the less energy it costs another atom to steal them
The atoms of different chemical elements can be differentiated based on the number of protons.
Each chemical element is differentiated by his number of protons. This number of protons is also knowing as atomic number and it is represented by the letter (Z).
The atomic number represented the number of protons in the nucleus of an element. For example:
- The element that has only 1 proton in his nucleus is Hydrogen atom.
- The element that has 2 protons in his nucleus is Helium atom.
<h3>What is an atom?</h3>
The atom is the smallest part of the composition of matter, it is indivisible and is composed of a nucleus that has protons and neutrons, and around the nucleus there are the electrons.

Answer:
1) Yes
2) No
Explanation:
A strip of solid magnesium metal is put into a beaker of 0.053M ZnSO4 solution-YES
A chemical reaction occurs
Mg(s) + ZnSO4(aq) ----------> MgSO4(aq) +Zn(s)
This reaction is possible because magnesium is far higher than zinc in the activity series of metals hence magnesium can displace zinc from a solution of a zinc salt.
A strip of solid zinc metal is put into a beaker of 0.058M MgBr2 solution. NO
A chemical reaction does not occur because magnesium is higher than zinc in the activity series hence zinc cannot displace magnesium from a solution of its salt.
