Because it has a fourth shell which means it's valence electrons are further from the nucleus (protons) meaning that there is less attraction between it's electrons and protons; this obviously forms a weaker bond. Sodium has only 3 shells which means its valence electrons are closer to the nucleus.
What else can I help you with?
Why does sodium corrode faster than iron?
Sodium corrodes faster than iron primarily due to its high reactivity as an alkali metal. It readily loses its outer electron, reacting vigorously with moisture and oxygen in the environment, leading to rapid oxidation. In contrast, iron, while it can rust, forms a protective layer of iron oxide that slows further corrosion. This inherent difference in reactivity and protective oxide formation explains why sodium corrodes more quickly than iron.
Is iron lighter than oxygen?
No, iron is not lighter than oxygen. Iron has a density of about 7.87 grams per cubic centimeter, while oxygen, in its gaseous state at standard temperature and pressure, has a density of about 0.00143 grams per cubic centimeter. This means that iron is significantly denser and heavier than oxygen.
Nuclear fusion only releases energy when elements that are lighter than what element are involved?
Nuclear fusion only releases energy when elements lighter than iron are involved. This is because elements lighter than iron release energy due to the process of fusion, while elements heavier than iron require energy to be input for fusion to occur.
What is lighter zinc or aluminum?
Aluminium. Zinc is around two and a half times heavier (more dense) than Aluminium.
How do you compare the element hydrogen with the alkali metal sodium?
dont know what kind of a comparision you are looking for but simply: Hydrogen has an atomic weight of 1.008 and sodium has an atomic weight of 22.99. the symbols are H for hydrogen and Na for sodium
Which is more malleable iron or sodium?
Sodium is more malleable than iron. Sodium is a soft metal that can be easily cut with a knife, whereas iron is a harder metal that is less malleable.
Which one is less malleable Sodium or iron?
Sodium is less malleable than iron. Sodium is a soft metal that can be easily cut with a knife and deformed, while iron is a much harder metal that is more resistant to deformation.
What is heavier iron or silica?
Iron is heavier because iron is a metal and metals are heavier but silica is not a metal so silica is lighter than iron.
What is the difference between helium and iron?
Helium is a gas that is lighter than air. Iron is a solid metal and is heavy.
Is lithium is lighter than iron?
Yes, lithium is lighter than iron. Lithium is a alkali metal with an atomic number of 3 and atomic mass of around 6.94 g/mol, while iron is a transition metal with an atomic number of 26 and atomic mass of around 55.85 g/mol.
Which is less malleable 1-sodium 2-iron 3- gold 4-silver?
Gold is less malleable compared to sodium, iron and silver. Gold is a soft metal with lower malleability than iron, silver, and sodium.
Which one is more malleabe iron or sodium?
Sodium is more malleable than iron. Sodium is a soft, highly malleable metal that can be easily flattened into thin sheets with a hammer or a rolling process. In contrast, iron is not as malleable as sodium and requires more force to shape into thin sheets.
Is steel lighter than lead?
Yes, steel is lighter than lead. Steel is a metal alloy made primarily of iron and carbon, whereas lead is a dense metal. This difference in composition leads to steel being less dense and therefore lighter than lead.
Is neon heavier than iron?
No. Neon is lighter than iron
How sodium is less malleable than iron?
Sodium is less malleable than iron due to its atomic structure. Sodium has a single valence electron in its outer shell, which makes it highly reactive and prone to forming ionic bonds with other elements. This results in a more brittle and less malleable structure compared to iron, which has a crystalline structure that allows for more flexibility and malleability in its atomic arrangement. Additionally, sodium is a softer metal than iron, further contributing to its lower malleability.
Who is less malleable sodium iron gold silver?
Gold is the least malleable of these metals, as it is known for its brittle nature and tendency to shatter when hammered. Sodium, iron, and silver are all more malleable than gold and can be easily shaped and flattened without breaking.
Are rubber plates lighter than metal plates?
Yes, rubber plates are generally lighter than metal plates.
