Where can you find the protons and neutrons?
the nucleus
Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the nucleus. Protons have a positive charge.
How many protons are in the potassium isotope 39 19k?
Answer and Explanation: 3919K 19 39 K has 19 protons and 20 neutrons.
How many protons and electrons does K+ have?
What is the number of electrons in K+?
19 electrons
So if you look for potassium (symbol K in the periodic table), you will find that it has the atomic number of 19. This tells you that potassium has 19 protons and – since the number of protons is the same as the number of electrons- also 19 electrons.
How many protons are in potassium 40?
The reason for this is that protons, like neutrons, like to exist in pairs in a nucleus. Potassium 40 contains odd numbers of both – 19 protons and 21 neutrons.
How do you find protons?
The easiest way to find the number of protons, neutrons, and electrons for an element is to look at the element’s atomic number on the periodic table. That number is equal to the number of protons. The number of protons is equal to the number of electrons, unless there’s an ion superscript listed after the element.
How do you find protons in an element?
The number of protons in an atom is equal to the atomic number of the element. For example, let’s use oxygen. According to the periodic table, oxygen has the atomic number eight. The atomic number is located above the element’s symbol.
