Iron is a chemical element and metal used in various applications, while "irons" typically refers to tools or devices made of iron, including golf clubs, branding tools, or handcuffs.
To complicate things a bit more, we sometimes find atoms of a chemical element that are a bit different to what we expect. Take carbon, for example. The ordinary carbon we find in the world around us is sometimes called carbon-12. It has six protons, six electrons, and six neutrons, ...
Iron is a specific chemical element, while metal encompasses a broad category of elements with shared properties like conductivity and malleability.
Find the number of electrons required to make up a charge of -32 micro C. An element that has the electron configuration (Ne)3s2 is in the group: a. 2. b. 5. Determine the number of (a) electrons, (b) protons, and (c) neutrons in iron (2656 Fe). ...

This was almost certainly the whiskey talking, but there’s an element of truth to my dumb declaration. Twin Sister are a true pop band’s pop band. There may not be any overt innovations in their music, but it’s so well conceived, so well crafted and, most importantly, so well ...
Chemically, the composition of Afghan emeralds is “astonishingly similar” to Colombian emeralds, SSEF said, adding only a careful trace element analysis of the stones would reveal the differences. The most common difference between the two is a higher iron concentration in the Afghan s...
Our Sun is a third-generation star. In other words, two stars lived and died before our Sun appeared. Whilst a star lives, it turns hydrogen into helium and then on to the next element in the periodic table. When fusing gets to Iron, it cannot transform anymore and, as such, dies, ...
The number of protons in an atom of any given element is always the same. Physicists call this theatomic number. So, in the above example of lead, its atomic number is 82 and that does not change; if it did, it would be a different element (thallium, atomic number 81, or bismuth,...
