What isotope has an atomic number of 86 and 136 neutrons? What is the atomic number, mass number, and number of protons of a neutral silver atom? What is the relationship between the number of protons and the atomic number? The mass number of an element is 18. It contains 7 electrons....
Atomic Number Is Not Atomic Mass or Atomic Weight If you look up an element in the periodic table, you'll see another number next to its atomic number. This is the atomic weight of the element, and it's usually twice the atomic number or more. Atomic weight isn't the same as atomic...

What is the atomic number?Atoms:Atoms are the basic unit of matter. Each atom has a dense nucleus composed of neutrons and protons. It also has a less dense outer electron cloud. Neutral atoms contain the same number of protons and electrons, which are positively and negatively charged, ...
An atomic number 1 points out that the atom is hydrogen. Similarly, an atomic number 2 reveals helium atom. The total number of neutrons and protons, when added together, gives us the relative atomic mass. For example, hydrogen holds a relative atomic mass of 1, whereas helium has a ...

To find the atomic number of the element with the electronic configuration 2, 8, 7, we can follow these steps: 1. Understand Electronic Configuration: The electronic configuration of an atom describes the distribution of electrons in its atomic orbitals. In this case, the configuration is given...
Atomic Structure:An atom is made up of three subatomic particles: protons, neutrons, and electrons. Inside the nucleus of an atom, the positively charged protons and the neutrally charged neutrons are found. Surrounding the nucleus are the negatively charged electrons. The b...
