Question

this element has 116 electrons. this element has one more proton than lithium (li). this element has 2 fewer protons than 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).

Explanation:

Step1: Recall atomic - number and proton - electron relationships

In a neutral atom, the number of electrons = number of protons, and the atomic number = number of protons.

Step2: Analyze each statement

Statement 1

If an element has 116 electrons, then it has 116 protons and atomic number 116. The element is Livermorium (Lv).

Statement 2

Lithium (Li) has an atomic number of 3. An element with one more proton has an atomic number of 4, which is Beryllium (Be).

Statement 3

Tennessine (Ts) has an atomic number of 117. An element with 2 fewer protons has an atomic number of 115, which is Moscovium (Mc).

Statement 4

The element with atomic number 6 is Carbon (C). The element directly below it in the periodic table has an atomic number of 14, which is Silicon (Si).

Statement 5

Phosphorus (P) has an atomic number of 15. An element with 2 fewer protons has an atomic number of 13, which is Aluminum (Al).

Statement 6

The element with atomic number 82 is Lead (Pb).

Statement 7

Boron (B) has an atomic number of 5. An element with 2 more protons has an atomic number of 7, which is Nitrogen (N).

Statement 8

Caesium (Cs) has an atomic number of 55. An element with one more proton has an atomic number of 56, which is Barium (Ba).

Answer:

1. Livermorium (Lv)
2. Beryllium (Be)
3. Moscovium (Mc)
4. Silicon (Si)
5. Aluminum (Al)
6. Lead (Pb)
7. Nitrogen (N)
8. Barium (Ba)
