The number of protons present inside an atom is equal to its atomic number, It is denoted by symbol Z. Mosely (1913) proposed the total positive charge on an atom is equal to its atomic number.
Atomic Number: The atomic number is equal to the number of protons in an atom. The atomic number is important because it identifies an atom as a specific element. Answer and Explanation:1 The atomic number of lithium is 3. This means that lithium has 3 protons. You can find the atomic ...

What is the atomic number of this helium atom? A neutral atom must have equal numbers of protons and electrons, so the atomic number of an element also gives the number of electrons. Helium has 2 protons, so its atomic number is 2. ...
I respond to Scerri's recent reply to my claim that there was a scientific revolution in chemistry in the early twentieth Century. I grant, as Scerri insists, that there are significant continuities through the change about which we are arguing. That is so in all scientific revolutions. But...
Step 3: Determine the atomic numberThe atomic number of an element is equal to the total number of electrons in a neutral atom. Therefore, the atomic number of the element with the outermost configuration 3d6 is 26. Final AnswerThe atomic number of the element with the outermost configuration...
In an electrically neutral atom, the atomic number (number of protons) is equal to the number of electrons. Why the Atomic Number Is Important The main reason the atomic number is important is because it's how you identify the element of an atom. Another big reason it matters is because ...
