A They are noble (inert) gases.
B They are nonmetals.
C They have the same thermal conductivity.
D They have the same number of protons.

Sagot :

The elements sulfur (S), nitrogen (N), phosphorus (P), and bromine (Br) have in common: B. They are nonmetals

Further explanation

The periodic system of elements is an arrangement of elements classified based on similar properties and their atomic number order.

The periodic system is divided into groups (vertical order) and periods (horizontal order)

  • Sulfur (S)

This element is located in group 6A and period 3 with atomic number 16

Electron configuration: [Ne] 3s² 3p⁴

Thermal conductivity: 0.205 W / (m · K)

  • Nitrogen (N)

This element is in group 5A and period 2 with atomic number 7

Electron configuration: [He] 2s² 2p³

Thermal conductivity 25.83 × 10⁻³ W / (m · K)

  • Phosphorus (P),

This element is in group 5A and period 3 with atomic number 15

Electron configuration: [Ne] 3s² 3p³

Thermal conductivity 0,236 W / (m · K)

  • Bromine (Br)

This element is located in group 7A and period 4 with atomic number 35

Electron configuration: [Ar] 3d10 4s² 4p⁵

Thermal conductivity: 0.122 W / (m · K)

Let's look at the answer choices

  • A They are noble (inert) gases

Noble gas is located in group 8A, so the above elements are not included in it

  • B They are nonmetals

In the periodic system, metal elements are located on the left and nonmetal elements are on the right.

In general, in a period from left to right, the metallic nature is reduced so that it is increasingly non-metallic

While in one group from top to bottom the greater the nature of the metal. Among metals and non-metals there is a semi-metallic element (metalloid)

The elements above are included in non-metallic elements

  • C They have the same thermal conductivity

Thermal conductivity is a value that indicates the ability of a material to conduct heat, its symbol k

Usually this value is to determine the conductor properties of a material. Generally a material is said to be a conductor if the material has a large k value of> 4.15 W / m ° C, especially in metals.

From the data above shows that there is a difference in the value of thermal conductivity

  • D They have the same number of protons.

The number of protons is proportional to the atomic number

atomic number = number of protons = number of electrons for neutral (uncharged) atoms

The elements above have different atomic numbers so the number of protons is also different.

Number of protons:

  • sulfur (S): 16
  • nitrogen (N): 7
  • phosphorus (P): 15
  • and bromine (Br): 35
