In all samples of the element potassium, each atom has. (1) 19 protons (Atomic #) (3) 39 protons and neutrons (14)) 6 protons, 8 neutrons, and 6 electrons. 39. number of neutrons. M. A. N. Neon. Ne. Protons: Electrons: Neutrons: Atomic Number: 10. Atomic Mass: 20.
Chlorine-35 accounts for 76% of the natural abundance of the element, with chlorine-37 making up the other 24% of the element. In its nucleus and its most … The ground state is the most stable energy state for the electrons Protons, electrons, and neutrons in a Fluorine-19 atom. John Smith. Try these on your own and check the answer below 78 Se 2-39 K + ANSWERS.
The atomic number gives the number of protons 19 p= 19 The atomic mass is the sum of the protons and neutrons p + n = 39 p= 19 put p into the equation and solve for n the neutrons. 19 + n = 39 Subtract 19 from both sides 19 -19 + n = 39 -19 n = 20 The number of electrons equals the number of protons in a neutral atom.

Step 1: For the number of protons, it is equal to the atomic number. You can look up the atomic number for any element on the Periodic Table of the Elements, or any Table of the Elements. Atoms are made of protons, neutrons, and electrons. Protons carry a positive electrical change, while electrons are negatively charged, and neutrons are neutral.

The proton forms the nucleus, while the electron orbits around it. a. an atom with 20 protons, 20 neutrons, and 18 electrons …
For a neutral atom, the number of protons is exactly equal to the number of electrons. So the number of electrons is the same as the atomic number.
