The average atomic mass of an element is the average mass of all the isotopes of an element. As we know, the atomic mass of an element is approximately the sum of protons and neutrons present in the nucleus.In an atom, each proton and neutron contribute around one amu, and the electronic mass, being so small, is negligible, so the …

There are 118 elements on the periodic table. Each element is identified by the number of protons in its atoms. This number is the atomic number. The periodic table lists the elements in order of increasing atomic number. Each element has a symbol, which is one or two letters. The first letter is always capitalized.

Melting point of Iron is 1538°C. Note that, these points are associated with the standard atmospheric pressure. In general, melting is a phase change of a substance from the solid to the liquid phase. The melting point of a substance is the temperature at which this phase change occurs. The melting point also defines a condition in which the ...

Protons and Neutrons in Iron. Iron is a chemical element with atomic number 26 which means there are 26 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.

B. False. Correct Answer. A. True. Explanation. Iron is a solid at room temperature because it has a high melting point of 1538 degrees Celsius and a boiling point of 2861 degrees Celsius. This means that at typical room temperatures, which range from around 20-25 degrees Celsius, iron remains in its solid state.
