The atomic mass of X₁ is 14 and the name of the element is Nitrogen.
The atomic mass of X₂ is 16 and the name of the element is Oxygen.
The atomic mass of X₃ is 32 and the name of the element is Sulfur.
The given parameters include:
weight C weight X
Compound 1 4.2 4.9
Compound 2 3.5 4.67
Compound 3 1.3 3.47
The atomic mass of the first compound (X₁) is calculated as follow;
let the total mass of X₁ and C = T
X₁ + C = T
X₁ + C = T
X₁ + 12 = 26
X₁ = 26 - 12
X₁ = 14
The atomic mass of X₁ is 14 and the name of the element is Nitrogen.
The atomic mass of the second compound (X₂) is calculated as follow;
let the total mass = P
The atomic mass of X₂ is 16 and the name of the element is Oxygen.
The atomic mass of the third compound (X₃) is calculated as follow;
Let the total mass = y
The atomic mass of X₃ is 32 and the name of the element is Sulfur.

Answer:
The different forms of an element based on the number of neutrons in the nucleus are called "isotopes." Carbon-12 is only one isotope of the element carbon, with 6 protons and 6 neutrons. There are also carbon-13, with 6 protons and 7 neutrons, and carbon-14, with 6 protons and 8 neutrons.

Answer:
La versión moderna de la tabla periódica de los elementos contiene los elementos ordenados según su número atómico creciente, y distribuidos en siete (7) filas horizontales llamadas períodos y dieciocho (18) columnas verticales llamadas grupos, de tal forma que los elementos en el mismo grupo tienen propiedades similares.

Answer:
d. a brittle solid.
Explanation:
Hello!
In this case, since cesium fluoride is widely known as an ionic compound due to the large electronegativity difference, it is possible to discard a. due to its crystalline structure, b. because conducting solids are metals, c. because ionic compounds are not likely to be gases and e. because even when it is soluble in water, the problem is not referring to an aqueous solution; therefore, the answer is d. a brittle solid.
