Question

tennessine (ts). this element is directly below the element whose atomic number is 6. this element has 2 fewer protons than phosphorus (p). the atomic number of this element is 82. this element has 2 more protons than boron (b). this element has one more proton than caesium (cs). this element has 5 protons in its nucleus. the atomic number of this element is 10. this element has 54 electrons surrounding its nucleus. this element has 4 more protons than silicon (si). this element has 2 fewer electrons than strontium (sr) surrounding its nucleus. the atomic number of this element is 31. this element has one less proton than arsenic (as). the atomic number of this element is 34. this element is found directly above the element whose atomic number is 34.

Explanation:

Step1: Recall atomic - number facts

The atomic number is equal to the number of protons. For a neutral atom, the number of electrons is equal to the number of protons.

Step2: Analyze each statement

• "This element is directly below the element whose atomic number is 6 (carbon, C). Carbon is in Group 14. The element below it is Tin (Sn) with atomic number 50, but it's not in the options.
• "This element has 2 fewer protons than Phosphorus (P). Phosphorus has an atomic number of 15, so the element has 15 - 2=13, which is Aluminum (Al).
• "The atomic number of this element is 82." The element with atomic number 82 is Lead (Pb).
• "This element has 2 more protons than Boron (B). Boron has 5 protons, so 5 + 2 = 7, which is Nitrogen (N).
• "This element has one more proton than Caesium (Cs). Caesium has 55 protons, so 55+1 = 56, which is Barium (Ba).
• "This element has 5 protons in its nucleus." The element with 5 protons is Boron (B).
• "The atomic number of this element is 10." The element is Neon (Ne).
• "This element has 54 electrons surrounding its nucleus." For a neutral atom, number of electrons = number of protons, so atomic number is 54, which is Xenon (Xe).
• "This element has 4 more protons than Silicon (Si). Silicon has 14 protons, so 14 + 4=18, which is Argon (Ar).
• "This element has 2 fewer electrons than Strontium (Sr) surrounding its nucleus. Strontium has 38 electrons, so 38 - 2 = 36, which is Krypton (Kr).
• "The atomic number of this element is 31." The element is Gallium (Ga).
• "This element has one less proton than Arsenic (As). Arsenic has 33 protons, so 33 - 1 = 32, which is Germanium (Ge).
• "The atomic number of this element is 34." The element is Selenium (Se).
• "This element is found directly above the element whose atomic number is 34 (Se). The element above Selenium in the same group is Sulfur (S).

Answer:

The elements corresponding to the statements from top - to - bottom are: Si, Al, Pb, N, Ba, B, Ne, Xe, Ar, Kr, Ga, Ge, Se, S
