The -2 you see on the sulfate ion reminds you that this molecule is charged. This negative charge comes from the oxygen atoms that surround the sulfur atom. An element can combine with other elements either by losing electrons or by gaining electrons in the outermost shell.
Phosphorus has 5 electrons in the outermost shell. So phosphorous either gain 3 electrons or lose 5 electrons phosphorous has 8 electrons in the second shell while combining. Oxygen is in Group 6. It has six electrons in its outer shell. It gains two electrons from one or two other atoms in reactions, forming an oxide ion, O They have the same structure as sodium chloride, with each atom having six neighbours.
Oxygen can be combined with various cations to form a large number of ionically bonded solids. SrO is a white solid, usually in powder form.
Strontium oxide will react in contact with water. It is slightly soluble in ethanol, but insoluble in acetone and ether.
In everyday life, iodide is most commonly encountered as a component of iodized salt, which many governments mandate…. Skip to content Common questions. April 22, Joe Ford.
