How many protons neutrons and electrons does Mo have?
The neutral atom of molybdenum has 42 electrons.
How does an atom of sodium has a larger mass than a atom of neon. how is this possible when neon has so many more valence 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.
Do valence electrons determine the atomic mass?
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.
What is the number of neutrons in an atom with atomic mass of 35 and three energy levels and 7 valence electrons?
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.

How many valence electrons does hafnium have?
Hafnium has 72 electrons and protons; the number of neutrons is different for each isotope and depend on atomic mass of the isotope.
How many protons neutrons electrons and valence electrons are found in oxygen?
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 related to the what a neutrons b valence electrons c protons d core electrons?
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.
