Question

Число нейтронов в атоме элемента с относительной атомной массой 55 на 5 единиц больше числа протонов. Определите период и группу где расположен этот элемент.

Answer 1

По условию число нейтронов 55, число протонов меньше на 5 . то есть -50. значит это элемент под номером 50. это марганец. он находится в 4 периоде и в 7 группе 

Answer 2

Number of Neutrons in an Atom

To determine the number of neutrons in an atom with a relative atomic mass of 55, which is 5 units greater than the number of protons, we need to calculate the number of protons first.

The number of protons in an atom is equal to its atomic number. Unfortunately, the atomic number of the element in question is not provided in the user's query or the search results. Therefore, it is not possible to determine the exact number of neutrons or identify the element without knowing its atomic number.

Period and Group of the Element

Similarly, without knowing the atomic number or the specific element, it is not possible to determine the period and group where the element is located in the periodic table.

The period of an element corresponds to the energy level of its valence electrons, while the group indicates the number of valence electrons. Both pieces of information are necessary to determine the period and group of an element accurately.

If you can provide the atomic number or the name of the element, I would be happy to assist you further in determining the number of neutrons and the period and group of the element.
