What else can I help you with?
Is an element the same thing as a molecule?
Yes. 7 non-metals: hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine, consist of a "diatomic molecule" of two identical atoms of that element. Sulfur, phosphorus, carbon, and few other elements do this too under certain conditions.
What are some elements with a single atom that cannot be combined?
When atoms combine to make molecules only the electrons adhere together to form bonds. The protons, neutrons, and nucleus do not combine.
Is channel-mediated diffusion a form of active transport?
Yes, when channels are specific for the structures of individual molecules it is active transport. Active transport cannot occur if the energy they are moving is not of the same type, like glucose cannot move calcium.
Can you see the atoms of elements with a powerful school microscope?
No, you cannot see individual atoms of elements with a school microscope. Atoms are much smaller than the wavelength of visible light, so they cannot be resolved by optical microscopes. Specialized techniques such as scanning electron microscopy or atomic force microscopy are needed to visualize atoms.
Why maltose sugar not ready for absorption?
Maltose is a complex sugar made up of two glucose molecules which cannot be directly absorbed into the body. Hence it needs to be broken down into two individual glucose molecules for ready absorption.
Why can't diatomic elements exist on their own?
Diatomic molecules cannot exist on their own because if they are alone they are very unstable and will react with any element very quickly.
Why is all compounds molecules?
All elements and compounds are present in molecular state. They cannot be found as individual atoms. Atoms cannot exist in free state.
Is all molecules compound?
All elements and compounds are present in molecular state. They cannot be found as individual atoms. Atoms cannot exist in free state.
What is the relationship between molecules and elements?
Elements are the basic building blocks of matter and cannot be broken down into simpler substances. Molecules are formed when two or more atoms of different or the same element chemically combine. In other words, elements are the individual components, while molecules are the combinations of these components.
What cannot be separated into its individual elements by physical means?
Chemical compounds or molecules cannot be separated into their individual elements by physical means. These substances require chemical reactions or processes, such as electrolysis or heating, to break the bonds between their constituent elements.
What cannot be seperated by physical means?
Elements
Which group of the periodic table contains elements that exist as diatomic molecules?
Ah, diatomic molecules are like best friends that always stick together! Elements in Group 17, also known as the halogens, are the ones that exist as diatomic molecules in their natural state. They form pairs, like H2, Cl2, and Br2, creating beautiful bonds that make them feel cozy and complete. Just like how we all need a friend to feel whole, these elements find comfort in each other's presence.
How was neptunium separated into individuals elements?
Neptunium is an individual element; isotopes of neptunium are not separated.
Is nitrogen gas a element or a compound?
Nitrogen gas consists of molecules, each of which consists of two atoms of the element nitrogen. Since a compound has to consist of two or more elements nitrogen cannot be a compound, by definition.
Explain why you call oxygen an element even though oxygen gas in the atmosphere is made from molecules?
Oxygen is considered an element because it consists of atoms with the same number of protons in their nucleus. While oxygen gas in the atmosphere is made up of diatomic molecules (O2), each molecule contains two oxygen atoms bonded together. These individual oxygen atoms are still considered elements because they cannot be broken down into simpler substances by ordinary chemical reactions.
Minerals made of only one element?
It's called an elemental mineral, like diamond (crystallized carbon) or gold.
What is formed of two atoms?
There are several types of diatomic molecules, that is molecules formed by two atoms. Molecules formed by two identical atoms are frequent like gaseous hydrogen and oxygen (H2 and O2) while other molecules are made by different atoms like carbon monoxide (CO), nitric oxide (NO), and hydrogen chloride (HCl). It is to be noted that diatomic molecules have to be distinct by substances that are not formed by separated molecules, but where two atoms are present in an equal stoichiometric ratio. For example, solid NaCl (that is common cooking salt) is a crystal with a number of sodium atoms equal to the number of chloride atoms. In a crystal a regular disposition of atoms of different kinds is present where individual molecules cannot be insulated.
