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).

Explanation:

Step1: Recall atomic number = number of protons = number of electrons in neutral atom

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

Step2: Analyze each statement

First statement

An element with 116 electrons has an atomic number of 116, which is Livermorium (Lv).

Second statement

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

Third statement

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

Fourth statement

The element with atomic number 6 is Carbon (C). The element directly below it in the periodic table is Silicon (Si).

Fifth statement

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

Sixth statement

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

Seventh statement

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

Answer:

1. Lv
2. Be
3. Mc
4. Si
5. Al
6. Pb
7. N
