Answer

Explanation:

Step1: Identify element based on protons

The atomic number (Z) is equal to the number of protons. For an atom with 4 protons, the element is beryllium (Be). Since it has 4 electrons, it is neutral. The mass - number (A) is the sum of protons and neutrons, so (A=4 + 5=9). The symbol is (^{9}Be), so the answer to question 1 is B.

Step2: Understand neutral atoms

All neutral atoms have the same number of protons and electrons. But this doesn't help to pick from the given options in a specific way as it's a general statement. However, the symbol of a neutral atom is just the element symbol with mass - number and atomic number.

Step3: Identify ion with 4 protons

An ion with 4 protons is beryllium. If it has a 2+ charge, it has lost 2 electrons. The number of neutrons is still 5 and the symbol is (_{4}^{9}Be^{2 +}), so the answer to question 3 is C.

Step4: Calculate neutrons for each option

For (^{36}Cl^{-}): Atomic number of Cl is 17, number of neutrons (n = 36-17 = 19). For (^{9}Be): (n=9 - 4=5). For ({4}^{9}Be^{2 +}): (n = 9 - 4=5). For (^{10}Be^{+}): (n=10 - 4 = 6). For ({18}^{36}): Assuming it's an atom of argon, (n=36 - 18=18). For (^{16}O^{2 -}): Atomic number of O is 8, (n=16 - 8 = 8). For (^{20}F^{-}): Atomic number of F is 9, (n=20 - 9 = 11). For ({15}^{26}): Assuming it's an atom of phosphorus, (n=26 - 15 = 11). C (({4}^{9}Be^{2 +})) and F ((^{16}O^{2 -})) do not have the same number of neutrons. A ((^{36}Cl^{-})) and E (({18}^{36})) do not have the same number of neutrons. B ((^{9}Be)) and D ((^{10}Be^{+})) have different numbers of neutrons. G ((^{20}F^{-})) and H (({15}^{26})) both have 11 neutrons, so the answer to question 4 is C.

Step5: Check protons and neutrons

For A ((^{36}Cl^{-})): 17 protons. For E (({18}^{36})): 18 protons. For B ((^{9}Be)): 4 protons. For C (({4}^{9}Be^{2 +})): 4 protons. For D ((^{10}Be^{+})): 4 protons. B, C, and D all have 4 protons but different numbers of neutrons (B has 5 neutrons, C has 5 neutrons, D has 6 neutrons), so the answer to question 5 is B.

Answer:

  1. B. (^{9}Be)
  2. N/A (general statement, no specific answer from options)
  3. C. (_{4}^{9}Be^{2 +})
  4. C. G & H
  5. B. B & C & D
