   Group 2 elements almost exclusively form ionic compounds containing the M 2 + ion, they are more reactive toward group 15 elements, and they have a greater tendency to form complexes with Lewis bases than do the alkali metals. Pure samples of most of the alkaline earth metals can be obtained by electrolysis of the chlorides or oxides.

   There are three types of strong chemical bonds: ionic, covalent and metallic. For ionic bonding the particles are oppositely charged ions. For covalent bonding the particles are atoms which share pairs of electrons. For metallic bonding the particles are atoms which share delocalised electrons. Ionic bonding occurs in compounds formed from ...

   How do elements form ions on the periodic table?

   • Moving from the far right to the left on the periodic table, elements often form anions with a negative charge equal to the number of groups moved left from the noble gases. For example, group 17 elements (one group left of the noble gases) form 1− ions; group 16 elements (two groups left) form 2− ions, and so on.

   Which Group 2 elements form ionic compounds that contain M2+ ions?

   • With their low first and second ionization energies, the group 2 elements almost exclusively form ionic compounds that contain M 2+ ions. As expected, however, the lightest element (Be), with its higher ionization energy and small size, forms compounds that are largely covalent. Some compounds of Mg 2+ also have significant covalent character.

   Which group of noble gases form 1 ions?

   • For example, group 17 elements (one group left of the noble gases) form 1− ions; group 16 elements (two groups left) form 2− ions, and so on. This trend can be used as a guide in many cases, but its predictive value decreases when moving toward the center of the periodic table.

   What is an ionic compound made up of?

   • An ionic compound is made up of charged particles, called ions. It has a giant lattice structure with strong electrostatic forces of attraction. Ions form when atoms lose or gain metal Shiny element that is a good conductor of electricity and heat, and which forms basic oxides.

   What are ionic and covalent compounds?

   • Under normal conditions, molecular compounds often exist as gases, low-boiling liquids, and low-melting solids, although many important exceptions exist. Whereas ionic compounds are usually formed when a metal and a nonmetal combine, covalent compounds are usually formed by a combination of nonmetals.
