Answer
1. No, changing the proton count changes the element.2. The atomic number is the number of protons in the nucleus of an atom.3. a. Protons = Atomic Number b. Mass Number = Protons + Neutrons c. Neutrons = Mass Number - Protons d. Electrons = Protons (in a neutral atom) or adjusted for charge (in ions) e. Charge = Protons - Electrons
Explanation
1. The proton count is fundamental to the identity of an element. Changing the proton count changes the element itself because the number of protons defines the atomic number, which is unique to each element.2. The atomic number is defined as the number of protons in the nucleus of an atom. It determines the chemical properties of the element and its place in the periodic table.3. To solve for: a. Protons: The number of protons is equal to the atomic number of the element. b. Mass Number: The mass number is the sum of protons and neutrons in the nucleus. c. Neutrons: The number of neutrons can be found by subtracting the number of protons from the mass number. d. Electrons: In a neutral atom, the number of electrons is equal to the number of protons. In ions, it is adjusted according to the charge. e. Charge: The charge of an atom or ion is the difference between the number of protons and electrons.
