Protons and neutrons are bound in a nucleus by the View Solution Total number of protons, neutrons and electrons present in 14 mg of .6C14 is : (Take NA=6×1023) View Solution What will be the total number of electrons , protons and neutrons in the product formed by the loss of ...
For a neutralatom, the number of electrons is the same as the number of protons. Often, the number of protons and electrons is not the same, so the atom carries a net positive or negative charge. You can determine the number of electrons in anionif you know its charge. A cation carrie...

Protons and neutrons make up the nucleus while electrons can be found outside the nucleus. Answer and Explanation: Strontium has an atomic number of 38. The atomic number of the element is equal to the number of protons which means that {eq}\displaystyle \rm......
1The table lists the number of protons, neutrons and electrons in several different particles.particle number of number of number of(not chemical protons neutrons electrons symbols)C101D332E777898G8108H91010Which of the particles, C, D, E, F, G and H in the table, fit each of the ...
The periodic table entry for each element has information on the total number of electrons, protons and neutrons it contains. The atomic number is equal to the number of protons and electrons for an uncharged atom. The mass number minus the atomic number
number of protons in the nucleus of each atom. 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.
