Question

На рисунке изображена модель атома Резерфорда для атома азота. Синими кружками обозначены электроны. В соответствии со схемой определите число протонов и нейтронов в атоме. У меня 7 электронов, объясните пожалуйста принцип решения З.Ы, и пожалуйста нюансы если тут есть химия подробно мне распишите. Я не могу в химию как Польша в космос

Answer 1

Азот в таблице Менделеева имеет 7 номер. Это означает, что атом имеет 7 электронов, а ядро 7 протонов. Число нейтронов определяется разностью между массовым числом и числом протонов( 14-7= 7 нейтронов)

Answer 2

Model of Rutherford Atom for Nitrogen

The Rutherford model of the atom depicts electrons orbiting around a central nucleus. In the case of the nitrogen atom, the model would show the arrangement of electrons around the nucleus.

Number of Protons and Neutrons in the Atom

In the Rutherford model, the number of protons in the nucleus determines the atomic number of the element, while the sum of protons and neutrons gives the atomic mass number.

Given that the nitrogen atom has 7 electrons, we can determine the number of protons and neutrons in the atom.

The atomic number of nitrogen is 7, which means it has 7 protons in its nucleus. To find the number of neutrons, we can use the atomic mass number of nitrogen, which is approximately 14.

So, the nitrogen atom has 7 protons and approximately 7 neutrons.

Explanation of the Principle

The Rutherford model of the atom is based on the concept of a central nucleus containing protons and neutrons, with electrons orbiting around it. The number of protons determines the element's identity, while the number of neutrons contributes to the atomic mass.

In the case of nitrogen, with 7 electrons, the nucleus would contain 7 protons. The atomic mass number of approximately 14 indicates that the nucleus also contains around 7 neutrons.

This model helps visualize the arrangement of subatomic particles within the atom and provides a basic understanding of atomic structure.

I hope this explanation helps! If you have further questions or need more details, feel free to ask.
