What else can I help you with?
What are used in a formula if the number of atoms of an element is more than one?
numbers
Is it possible for an element to have more than 1 atomic formula?
No, each element has a unique atomic formula based on the number of protons in its nucleus, which is called the atomic number. This atomic formula is represented by the element's chemical symbol.
How does the composition of most minerals differ from the pure element?
Minerals (other than elemental minerals) are combinations of elements.
Is bronze in the periodic table?
No, since bronze is an alloy of more than one metal, and not an elemental metal.
What is the meaning of displacement reaction?
A displacement reaction is a type of chemical reaction where a more reactive element displaces a less reactive element from a compound. This occurs when the more reactive element has a greater tendency to lose electrons and form positive ions than the element it displaces. The displaced element is often in elemental form.
How is an element represented in a chemical formula?
Each atom has its own elemental 'symbol' or 'formula', there are more than 92 elements: from number 1. Hydrogen (H) to number 92. Uranium (U). Examples: O for oxygen, C for carbon, N for nitrogen atoms.
Element M reacts with chlorine to form a compound with the formula MCl2 It is more reactive than magnesium and smaller than barium This element is?
Element M is calcium. It reacts with chlorine to form calcium chloride (CaCl2). Calcium is more reactive than magnesium and smaller than barium on the periodic table.
What element contains more than one element and has metallic properties?
No element contains more than one element.
What is barium's chemical formula?
Barium is an element, it has no chemical formula other than 'Ba'.
Is ch4 an compound or a element?
CH4 is a compound. (hint: if the formula has more than one capital letter, it contains more than one element and is therefore a compound.)
What planets have more than one element?
Many of the planets have more than one element. Two of these planets that have more than one element are Earth and Jupiter.
Nonmetal ions larger than their elemental counterparts?
Non metallic ions are negatively charged. They have more electrons than protons. So they are larger than elemental counterparts that have equal number of protons and electrons.
