[1 mark] _____ 6. The number of protons in one atom of an element determines the atom’s , and the number of electrons determines of an element. Atomic structure. These are positively charged particles. It also tells you the number of _____ in a neutral atom of that element. üéttire of some substances by complet- ing the chart below. So, Question 4. In the Modern Periodic Table – atoms of all elements are arranged according to the their increasing order The 3 particles of the atom are: prcions (Ð (o Their respective charges are: The number of protons in one atom of an element determines the atom's number Of electrons determines the of the elemen in one atom of an element. 1 Electromagnetic Radiation . The periodic table is as useful for predicting properties of undiscovered elements today as it was in An atom's likelihood of gaining an electron; the energy change that happens when an atom gains an electron (When an atom gains an electron, it becomes a negative ion) Formation of Ions When atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells (If gain e-, atom becomes a negatively charged ion.
