There are a lot more differences than similarities between ionic and molecular compounds, but let's start with the similarities. Both have a non-metal in them and both compounds are formed by the atoms trying to achieve a state of 8 (or 2) electrons in their valence (outer) shell. The differences are numerous and basically define the two branches of chemistry, inorganic and organic. Ionic compounds are inorganic. They are formed by combining metals (+ ions) with nonmetals (- ions). They are soluble in water (polar), conduct electricity in solution, and have high melting (freezing) and boiling points. Organic compounds are molecular also called covalent.
The Raspberry Pi is a low-cost credit-card sized single-board computer. The Raspberry Pi was created in the UK by the Raspberry Pi Foundation. The Raspberry Pi Foundation's goal is to advance the education of adults and children, particularly in the field of computers, computer science and related subjects..
Techopedia explains Raspberry Pi. The Raspberry Pi debuted in February 2012. The group behind the computer's development - the Raspberry Pi Foundation - started the project to make computing fun for students, while also creating interest in how computers work at a basic level. Unlike using an encased computer from a manufacturer, the Raspberry Pi shows the essential guts behind the plastic.
