True
No, metals are not compounds. They are elements or mixtures (alloys) containing metallic elements.
True. Binary ionic compounds consist of a positively charged metal ion and a negatively charged nonmetal ion. These ions usually come from opposite sides of the periodic table.
false
False. Most minerals are compounds, which means that they are combinations of elements. Additionally, some minerals are elements by themselves.
No, binary ionic compounds are made up of positively charged metal ions and negatively charged nonmetal ions. While metals can form ionic compounds with nonmetals, not all metals are involved in forming binary ionic compounds.
false
False. Elements are made up of only one type of atom, whereas compounds are made up of different types of atoms chemically bonded together. Elements do not link up to form compounds.
The statement that all compounds have a composition of ionic compounds is false. Many compounds can be covalent in nature, where atoms share electrons instead of transferring them. On the other hand, it is true that compounds have a definite composition with fixed ratios of elements and compounds are formed by the bonding of two or more different elements.
True. Elements have a uniform composition because they consist of only one type of atom, which gives them consistent properties throughout. This uniformity distinguishes elements from compounds and mixtures, which can contain different types of atoms or molecules.
False. Hydrogen and oxygen - both gases - combine to form water - a liquid.
no they dont chane
False. Most minerals are compounds, meaning they are composed of two or more elements bonded together. This is what gives minerals their unique chemical and physical properties.
