In side protons there is 99% of free space only presented. but remaining part consist of quarks that quarks are inter connected with some bonds which are look like a springs.
4 protons.
Iron has 26 protons.
protons are present in the nucleus while electrons are present around the nucleus
27 protons atomic number = number of protons
protons and nuetrons are equal to no. of electrons present in atom
The number of protons present in an ion is equivalent to its atomic number.
19 Protons and 20 electrons
Protons and neutrons are present in nucleus. They are fixed.
20 protons and 20 electrons are present in calcium.
electrons, neutron, protons
maybe because they are 2 DIFFERENT particles present in an atom... electrons are -ve while protons are +ve ly charged
It is nothing but the total no of protons and electrons .So it is found by summing the total no protons and electrons present in an atom It is not electrons but the total of neutrons and protons present in the nucleus of any atom.
