What are some examples of an atomic element?

Most elements are atomic elements, which means that they naturally exist as single atoms, not molecules. For example, neon, (Ne), helium (He), iron (Fe).

What are different atomic forms of an element?

Isotopes are different atomic forms of the same chemical element. The key difference between isotopes and elements is that the isotopes are different forms of the same chemical element whereas the elements are species of atoms having the same number of protons in the atomic nuclei.

What are some examples of elements and their atomic number?

Examples of elements include iron, oxygen, hydrogen, gold , and helium . An important number in an element is the atomic number. This is the number of protons in each atom. Each element has a unique atomic number. Hydrogen is the first element and has one proton, so it has an atomic number of 1.

What makes an atom a specific element?

Answered by. itemderby. Answer: Option (a) is the correct answer. Explanation: Number of protons is the one factor which identifies an atom as a specific element. For every neutral atom, the number of protons equals the number of electrons. Therefore, either of them helps in identifying an atom’s atomic number hence an atom can be detected.
