carbon is formed
This is a monoatomic ion.
The element in period 4 group 5 (also known as Group 15) will typically form an ion with a 3- charge, known as a nitride ion. This is because elements in this group tend to gain three electrons to achieve a stable electron configuration.
It is an element, it can become an ion, but it is usually just an element combined with 02 after mixing with the atmosphere.
+3 ion
Pb is the elemental symbol for lead. In this form, lead is neither a cation or an anion - it is neutral. However, lead acts like a metal and when it becomes an ion, it tends to form a cation by giving up electrons and becoming positively charged.
every element
Sodium forms 1 type of ion; namely, Na+.
which element can only formed one ion
Na+ is not a molecule; it is an ion, specifically a sodium ion.
This is a monoatomic ion.
(209) Po+4 The number of protons in an atom, ion, or molecule cannot change no matter what. Every Polonium atom and ion in the entire world has 84 protons. You find which element has 84 protons by looking at the 84th element on the periodic table. Now, every atom also has the same number of protons and electrons, but since this example is an ion, it must have more or less electrons than protons. Since there are 4 fewer electrons than protons, that means the ion is positive. So it would be Polonium with a +4 charge. the 209 is the atomic mass of the atom. There are several different isotopes of polonium. This one has 84 protons and 125 neutrons, thus you add them together to get the atomic mass of 209 amu.
The most common ion is Po++++ but it can also have valency +2 or +6.
disappear
Calcium is a group 2 element, and so it will form a cation, Ca 2+.
+3 ion
The element in period 4 group 5 (also known as Group 15) will typically form an ion with a 3- charge, known as a nitride ion. This is because elements in this group tend to gain three electrons to achieve a stable electron configuration.
