Ionic means the elements are joined by connecting with electrons, and everything is molecular. Molecular means something to do with molecules, which is a single compound, which can be carbon dioxide to, zinc oxide. Elements is a single pure element from the Periodic Table, like oxygen,carbon, florine, zinc, iron etc. Compound is a group of these elements bonded through either ionic or covalent bonding. So lactose is just a compound that has joined both ionically and covalently
No, lactose is not a noncaloric organic compound; it is a disaccharide sugar composed of glucose and galactose. As a carbohydrate, lactose provides energy and contains calories. It is commonly found in milk and dairy products, contributing to their caloric content.
When you mix an element with a compound, a chemical reaction may occur. The element may react with the compound to form a new compound or may remain unchanged depending on the reactivity of the elements involved.
An element is a part of a compound.
It is an element.
When you mix an element with a compound, the element will interact with the components of the compound but will not form a new compound itself. It may bond to some parts of the compound or remain unchanged depending on the specific elements and compounds involved in the mixture.
lactose

No, lactose is not a noncaloric organic compound; it is a disaccharide sugar composed of glucose and galactose. As a carbohydrate, lactose provides energy and contains calories. It is commonly found in milk and dairy products, contributing to their caloric content.
KCl is a compound not an element.
Beryllium is an element. It is not a compound
cornstarch is a compound element.
First of all you have mispelled it as 'hellium' . It is 'HELIUM'. It is an element. It atomic No. is '2' , so therefore it is found in position number '2' in the Periodic Table, as 'He'. It is neither a compound nor a mixture. The chemical symbol for helium is 'He '. It's Atomic Mass is '4' It is compsed of 2 protons, 2 neutrons and two electrons. It is the MOST Noble(Inert) of all the elements. It does NOT react with anything. Therefore it exists 'monatomically' (single atoms). Its condensing point is 7 K ( - 266 oC) (Becomes a liquid) Its freezing point is 4 K . ( - 269 oC) (becomes a solid). The name 'helium' is from Classical Greece, and means 'from the Sun'(Helios), because two hydrogen atoms fuse together in the Sun , they form 'Helium'.
Mixture
if it dissolves its a compound if not its an element.
NO = Nitrous Oxide - compound No = Nobelium - element
It is a compound Carbon is an element.
salt is a compound. it is not an element
