Question

question 6 (1 point)
what is determined by the proton(s) of an element?
o a chemical properties of the element
o b mass of the element
o c number of valence electrons of the element
o d atomic number of the element

Explanation:

• The atomic number of an element is defined as the number of protons in its nucleus.
• Chemical properties are mainly determined by the valence electrons.
• The mass of an element is related to the sum of protons and neutrons.
• The number of valence electrons is not directly determined by the number of protons alone (though it is related in a neutral atom as the number of electrons equals the number of protons in a neutral atom, but the concept of valence electrons is about the outermost electrons which is a more complex electron - shell related concept).

Answer:

d. Atomic number of the element
