What determines the atomic number of an atom? A. Number of electrons in the other shell. B. Mass of the atom. C. The number of neutrons. D. The number of protons. E. The number of protons plus neutrons. The ___ is the ...
7 Which statement about an atom is correct? c A The nucleon number is smaller than the proton number. B The nucleon number is the sum of the number of protons and electrons. C The number of proton always equals the number of electrons. D The number of proton always equals the number ...
The atomic number of an element is equal to the number of protons in its nucleus. In a neutral atom, the number of protons equals the number of electrons in shells which is the energy level around the nucleus. Isotopes are atoms with the same atomic number but distinct neutron numbers, ...
Follow these simple steps to find the number of protons, neutrons, and electrons for an atom of any element.
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 ...
Whereas this correlation does express a causal relationship, this relationship is merely the requirement that the number of electrons equals the number of protons in neutral atoms. The observed covariance is the result of increased nuclear stability at even atomic number and the decrease in the ...
