Is it possible to identify something as an element

No and Yes. Metal is a generic term given to something metallic. As such a metal my not be a pure substance, metals are frequently alloyed. However, it is possible to have a particular metal that is a pure substance. The smallest possible unit of a covalent compound is a molecule.

A tree diagram is the way to identify and count all possible outcomes. An atom is the smallest particle possible of a pure substance. A molecule is the smallest possible particle of a compound.

It is in fact a compound. No, that would not be possible. Historically they were classed with nouns. They are descriptors and add to what is being said. To identify and describe something. This compound is hypothetical and is not possible it is P4O No, there is only one possible configuration for a compound with the formula NH3. An isomer is a substance for which there are more than one configurations for the same chemical formula.

What are two possible ways to seperate a compound or a mixture into the elements. A chlorinating compound is something that adds a chlorine atom to another compound.

There are many possible ones, and it depends on what type of thing you want to add chlorine to. The ultimate chlorinating compound is chlorine gas itself Cl2 , but it is both extremely corrosive and toxic, and so not good to work with if you can avoid it. It is possible. This gives each element a unique fingerprint, making it possible to identify the elements present in a container of gas, or even a star.

We can use tools like the periodic table of elements to figure out exactly how many protons, and thus electrons, an atom has. First of all, we know that for an atom to have a neutral charge, it must have the same number of protons and electrons. If an atom loses or gains electrons, it becomes ionized, or charged.

The periodic table will give us the atomic number of an element. The atomic number tells us how many protons an atom has. For example, hydrogen has an atomic number of one - which means it has one proton, and thus one electron - and actually has no neutrons.

For the Student Based on the previous description of the atom, draw a model of the hydrogen atom. The "standard" model of an atom is known as the Bohr model. Different forms of the same chemical element that differ only by the number of neutrons in their nucleus are called isotopes. Most elements have more than one naturally occurring isotope.

Many more isotopes have been produced in nuclear reactors and scientific laboratories. Isotopes usually aren't very stable, and they tend to undergo radioactive decay until something that is more stable is formed. You may be familiar with the element uranium - it has several unstable isotopes, U being one of the most commonly known.

The means that this form of uranium has neutrons and protons combined. If we looked up uranium's atomic number, and substracted that from , we could calculate the number of neutrons that isotope has.

Here's another example - carbon usually occurs in the form of C carbon , that is, 6 protons and 6 neutrons, though one isotope is C, with 6 protons and 7 neutrons.

Different ions and isotopes will alter the number of neutrons and electrons, making these properties unreliable identifiers. Similarly, atomic mass will vary with the number of neutrons present and cannot be used to establish atomic identity.

Diatomic elements are commonly referred to as diatomic gases because whenever they are by themselves, they bond to themselves that is where the "2" subscript comes from. Anytime diatomic elements have that "2" subscript, they have the gas g phase label.

For example,. The symbol for potassium comes from the latin word for potassium, kalium. That is why the chemical symbol for potassium is. The word for iron in latin is ferrum, thus, the chemical symbol for iron is because of its latin name. Remember, the number of protons is equal to the atomic number of the element.

Look at the periodic table and find the element with atomic number 42, it corresponds to molybdenum. Since atoms are neutral, the number of electrons must equal the number of protons to balance the negative and positive charges. Thus the element with 17 electrons also has 17 protons. The number of protons is equal to the atomic number of the element.

Use the periodic table to find the element with atomic number 17, chlorine. Note that ions are not neutral, thus they have unequal numbers of protons and electrons. Also, isotopes of the same element contain differing numbers of neutrons, which also affects the weight of the isotope.

Email address: Your name:. Example Question 1 : Identifying Elements. Which of the following defines the identity of an element? Possible Answers: Number of neutrons. Correct answer: Number of protons.

Explanation : The identity of an element is determined by the number of protons. Report an Error. No, as some compounds such as carbon dioxide and oxygen are completely transparent, you can not see them and can not distinguish between the two with just the naked eye.
