What causes properties of elements?
The chemical properties of an element are due to the distribution of electrons around the atom’s nucleus, particularly the outer, or valence, electrons; it is these electrons that are involved in chemical reactions. Some properties of an element can be observed only in a collection of atoms or molecules of the element.
What causes elements to form compounds?
The answer is that compounds are formed when elements are joined and held together by strong forces called chemical bonds. Covalent bonds share electrons between atoms in order to fill their electron shells. In the compound, molecules are held together by the attraction between the nucleus and the shared electrons.
What makes up one element?
Matter can be made up of a single element or a combination of many different elements. Each particle of a particular element cannot be broken down into simpler substances by ordinary physical or chemical processes. Some examples of elements that you might recognize are oxygen, carbon, helium, mercury, copper, and gold.
What causes atoms to combine?
Why exactly do atoms tend to combine together? Atoms form chemical bonds with other atoms when there’s an electrostatic attraction between them. This attraction results from the properties and characteristics of the atoms’ outermost electrons, which are known as valence electrons.
What element is most things made of?
The most abundant element in the universe is hydrogen, which makes up about three-quarters of all matter! Helium makes up most of the remaining 25%. Oxygen is the third-most abundant element in the universe. All of the other elements are relatively rare.
How do elements get excited when they meet different substances?
Every elements get excited when it meets different ion, however, not every ion can cause reaction to the element or produce different color. For example, only when an element meets metal ion that it will get excited and produce different color. Therefore, the ion of the stuff that the element meets will create different color of light.
How does lighting affect the way elements deliver light?
The color temperature of the room or the place will influence the visual trick of the light. That is why some people may see blue in purple when the lighting is a bit reddish and many more. Thus, we can conclude that the way elements deliver light is also influenced by the illumination.
Why do different elements produce different colors?
By this way, the color produced is different from other elements. The lights travel on different line of spectrum that produce different color. That is why that when the energy level rises from the excitement to heat, the element begins to produce the light according to its reaction to the energy level and line of spectrum.
Why did the ancient Greeks believe that the elements were unchanging?
Although the Greeks believed that the four elements were unchanging in nature, everything was made up of different elements, which were held together or pushed apart by forces of attraction and repulsion, causing substances to appear to change. This is similar to what really happens with elements and all molecules at an atomic level.
