What is oxygen extensive properties? Oxygen: Oxygen is a gaseous element that is colorless, odorless, and tasteless. It constitutes 21% of air and also found in water. However, oxygen has the capacity to combine all elements other than inert gases. It has atomic number 8 and represented by...
The quantum mechanical approach is currently used to explain atomic structure. The study of fundamental constituents such as atoms, molecules, substances, metals, crystals, and other aggregates of the matter is where traditional chemistry begins. Let’s now see about some basic terms of chemistry a...
Which element is a member of the same family as oxygen whose most stable ion contains 54 electrons? What element is the most abundant noble gas in the air? Which element below has five valence electrons? a. Si b. Se c. S d. I e. Sb ...
I'm just speculating though. I don't think they have actually figured out how a shark's sensory system works, completely. Bylluviaporos— On Dec 03, 2011 The one thing I know about electronegativity is that it is the opposite of electropositivity (which is the likelihood of an element to...
He is a noble man who would never put his family in jeopardy. Humble Thinking lowly of one's self; claiming little for one's self; not proud, arrogant, or assuming; thinking one's self ill-deserving or unworthy, when judged by the demands of God; lowly; waek; modest. God resisteth...
The following figure is a typical structure of a resistive gas sensor, which is mainly composed of a SnO2 sensitive element, a heater, an electrode, a base, and a stainless steel mesh cover. This sensor has a simple structure, easy to use, and can detect reducing gas, flammable gas, ste...
Water is made up of two different elements, 2 hydrogens and 1 oxygen, so H2O is a compound. Two oxygen atoms (O2) are two elements, but they are the same element, so O2 is a molecule. Iron oxide (Fe2O3), or rust, is made up of two different elements, 2 irons and 3 oxygens...
What do a wedding ring, an old-fashioned light bulb and a drill bit have in common? They each can be made of tungsten. Tungsten is an element that, on its own, is a very hard, very heavy, and highly heat-resistant metal. These special properties of tungsten are exactly what make it...
Oil and gas are both fossil fuels used as primary energy sources, but oil is generally used in liquid form for fuels and manufacturing, while gas, typically found as natural gas, is used for heating, electricity, and industrial processes.
Atoms are the fundamental unit of an element. They consist of a nucleus and surroundingelectrons. When an atom has an incomplete electron shell, it is said to have valence electrons. When two or more atoms come together to share outer shell valence electrons, a chemical (covalent) bond is ...
