How do you know the number of protons electrons and neutrons in the 1st 20 elements?
Look at the Periodic Table.The bottom number on an element is the number of protons. The number of electrons will be the same. Subtract the bottom number from the top number to get the number of neutrons. e.g:
103
Rh
45
Protons= 45
Electrons= 45
Neutrons= 58 (103-45)
What else can I help you with?
Are protons neutrons and electrons elements?
No, protons, neutrons, and electrons are not elements. Protons and neutrons are subatomic particles found in the nucleus of atoms, while electrons orbit the nucleus. Elements are substances made up of one type of atom, characterized by the number of protons in their nucleus.
What particles make up the mass of an atom?
The number of protons
What are elements having same number of protons and neutrons called as?
Carbon Number of Protons/Electrons: 6 Number of Neutrons: 6
What are the subatomic particles of astatine?
As for all other elements: neutrons, protons and electrons.
What are the number of protons neutrons and electrons in boron?
Boron has 5 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a boron isotope = Mass number - 5

What element is composed of atoms with the same number of neutrons or protons?
Ideally, all elements should have the same number of protons, neutrons and electrons unless they become ionic. This is how elements such as the noble gases remain stable. They the same number of electrons, protons, and neutrons, and a full octet.
What particles make up the mass of an atom?

What is the number of protons electrons and neutrons in n-14?
Nitrogen-14: 7 Protons, 7 Electrons, 7 Neutrons To work this out in the future for other elements: Protons = Atomic Number Electrons = Atomic Number Neutrons = Atomic Mass - Atomic Number Hope this helps!

What are the number of protons neutrons and electrons in an element?
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
Do electrons equal the sum of the number of neutrons and protons in an isotope?
No. The number of neutrons has no affect on the number of protons and electrons.
What is the number of neutrons electrons and protons in nitrogen14?
there are 7 neutrons, 7 protons, and....----electrons
How many protons electrons and neutrons does americium have?
Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number of protons
What is the number of protons neutrons and electrons of carbon 12?
Carbon-12 has 6 protons, 6 neutrons, and 6 electrons. The number of protons determines the element (carbon), the number of neutrons plus protons gives the mass number (12), and in a neutral atom, the number of electrons equals the number of protons.
What are the number of protons neutrons and electrons in boron?
Boron has 5 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a boron isotope = Mass number - 5
