Cs (Caesium) is the most reactive!!!!
No, if whatever you are looking for does not appear on the Periodic Table of Elements then it is not an element.
No, androids is NOT an element or type of element. Perhaps you are referring to actinoids, which are a group of elements that appear in the periodic table.
Brass is an alloy of the elements copper and zinc. Alloys do not appear on the periodic table. Copper is an element with the symbol Cu and zinc is an element with the symbol Zn. They both appear on the periodic table.
The most reactive element among cesium (Cs), barium (Ba), and lutetium (Lu) is cesium (Cs). Cesium is located at the far left of Period 6 in the periodic table and has a single valence electron, which makes it highly reactive.
Water isn't an element. It is made up of Hydrogen and Oxygen, both of which are elements and appear on the periodic table.
An element is a primary constituent of matter and would appear on the periodic table. French dressing does not appear on the periodic table and is therefore not an element. A compound is a substance formed when two or more elements are chemically bonded together. French dressing is not the chemical bonding of two or more elements. This leaves mixture and this is what french dressing is
J Q appears in some older periodic tables as 'Unq' (unnilquadium), the temporary name for what is now called Rutherfordium (At. no. 104).
Electron configuration is the arrangement of elements according to their increasing atomic numbers whiles period is the arrangement of elements according to the increasing number of valence electrons.
There is no such thing as Kl ins chemistry. KI (with a capital I) is potassium iodide, but since it is a compound and not an element it does not appear on the periodic table. Its component elements, potassium (K) and iodine (I) do appear on the table however.
As it is a periodic table of elements and sodium chloride is a compound consisting of sodium, chlorine and oxygen, sodium chloride does not appear on the periodic table.
In the periodic table only the chemical elements appear; but tables for isotopes also exist.
Yes, salt is not listed as an element on the periodic table. Sodium (Na) and chlorine (Cl) are the elements that combine to form salt (sodium chloride), but the compound itself is not listed on the periodic table.
