an element and an atom are different but related because a particular element is made up of many different types of atoms

I need help on ths question

Answer 1

I am not sure if your statement is valid...it appears to be something that you think rather than a question from a text-book.

 

Technically, an element is defined as "A substance that cannot be broken down into simpler substances by chemical means. An element is composed of atoms that have the same atomic number, that is, each atom has the same number of protons in its nucleus as all other atoms of that element".

 

So for instance you have the element Oxygen or Hydrogen. The two of them combine to give a compound called water but each of them cannot be simplified into anything simpler than Oxygen or Hydrogen respectively. 

 

Atoms of the same element may have isotopes, i.e., atoms with different number of neutrons but with the same atomic number (number of protons).

 

Answer 2

I know you've been answered but I thought this may help you a little. An element is a kind of atom with a certain number of protons. If we say that an atom is a car, then the elements could be like Mustang, Subaru, Toyota. Not all mustangs are the same exactly, but they have one thing that makes them all mustangs. For an element, that is the number of protons. If you remove a proton from an atom you've made a new element. 

 

How are elements and atoms related? Because the element is telling you what kind of atom you have and how it will behave (how it reacts to things, its size and mass, etc). You can't have an atom without it being of some element.

Answer 3

An element is identified by the number of protons in its atoms.  A sample of an element can have isotopic forms of atoms.

 

Isotopes are atoms that have the same number of protons in their nuclei, but different numbers of neutrons.  For example,  the carbon within the human body is composed of mainly three isotopes: C12 , C13, and C14.  C14 is a radioactive form of Carbon whose concentrations are measured by specialists when estimating the age of specimen samples.

 

The molar mass measures large-scale, visible quantities of elements (individual atoms are too small to be handled).  The molar mass of carbon is 12.011 grams because this value is the takes into account the percent% of the isotopes within a 1 mole mass of Carbon (primarily 99% C12, C13 and C14 make up the remaining 1%).
