3 valance electrons,13 electrons,13 protons,14 neutrons
The neutral atom of molybdenum has 42 electrons.
sodium has more protons and neutrons. electrons have practically no mass, valence electrons are just outer orbital electrons. sodium has 11 protons, 11 electrons, and 12 neutrons. Mass is 23. neon has 10 protons, 10 electrons, and 10 neutrons. Mass is just 20. The neon atom has 10 protons and 10 neutrons for a mass number of 20. The sodium atom has 11 protons and 12 neutrons for a mass number of 23. The number of valence electrons has no bearing on mass number or atomic weight.
No, the valance electrons determine the charge, the atomic number is determined by the number of protons. Generally, electrons are equal to protons, but in ions it is different, so use protons.
There are 18 neutrons. If the valence level has 7 electrons, that means the first is full, and always has 2(unless its hydrogen which has 1) and the second will be filled with 8 making 17 total. Since the electrons always equal protons we know there are 17 protons. Since atomic mass is protons plus neutrons, and atomic mass is 35 we minus 17 form 35 and have 18.
Beryllium (Be) has 4 protons and 2 valence electrons.
it has 19 electrons and 19 protons and 20 neutrons
The gaseous element with 5 valence electrons and fewer neutrons than sodium is Boron. Boron has 5 protons and 5 neutrons, while sodium has 11 protons and about 12 neutrons.
Nitrogen14, has 7 protons, 7 electrons and 7 neutrons.

Hafnium has 72 electrons and protons; the number of neutrons is different for each isotope and depend on atomic mass of the isotope.
Oxygen has 8 protons and electrons; six electrons are valence electrons.Depending on the natural isotope oxygen has 8, 9 and 10 neutrons
The chemical properties of an atom are primarily related to its valence electrons. These are the electrons in the outermost energy level and are involved in chemical bonding and reactions. The number of protons in the nucleus determines the element's identity, while core electrons play a role in the atom's stability but do not significantly impact its chemical behavior. Neutrons mainly contribute to the atom's mass and stability.
