Concept 2.1 Matter consists of chemical elements in pure form and in combinations called compounds

1. Define science – Science is the development of concepts about the natural world , often by using the scientific method

Matter is defined by Lucretius as a primordial entity free of void and decay; they are the atoms that create entities. Atoms and primordial entities are synonymous with each other: the solidity of matter is called “procreant atoms, matter, seeds of things, or primal bodies, as primal to the world” (107-108). Lucretius uses all these words, emphasizing the simplicity of his philosophy. This simplicity is explained as he declares: “primal bodies are solid, without a void” (596). Because he believes that all entities are composed of primal bodies and a void, the primal body must be free of any void, thus giving substance to the object. He declares that entities are composed: “partly primal germs of things, and partly unions deriving from the primal germs” (566-567). This definition states that all matter consists of atoms, which, when combined, form molecules. Molecules, as defined by science, are the “unions” of atoms. This scientific principal is further explained: “So primal germs have solid singleness, which tightly packed and closely

A) They feature carbon atoms which are covalently bonded to hydrogen (Open Learning Initiative, 2015, pg.63).

Matter is often defined as mass that can be physically observed by the senses, it can be measured scientifically and is tangible , it could be said the material world unlike aspects of social worlds is less abstract and easier to define, for example a building which comprises of bricks, wood, metal and other materials built into a specific shape compared to a community which can relate to people of the same place or shared values or interests or all. That is not to say that matter just is, it too can have agency and varying meanings dependent upon the

11.Describe the three different types of bonds, providing examples of molecules formed through each type of bond. (3 points)

States of matter are the distinct forms that different phases of matter take on. Historically, the distinction is made based on qualitative differences in bulk properties. Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter maintains a fixed volume but adapts to the shape of its container; and gas is the state in which matter expands to occupy whatever volume is available.

Matter is defined as anything that occupies space and can be perceived by one or more senses; a physical body, a physical substance, or the universe as a whole. There are four distinct states of matter: solids, liquids, gases, and plasma. There are other states of matter such as Bose-Einstein condensates and neutron degenerate matter, but those states can only be found under extreme conditions.
