Answer 2

The Correct Statement about Lithium Atoms

The correct statement about lithium atoms is (В) в атомі літію не мають негативний заряд. Lithium atoms do not have a negative charge.

Explanation

Lithium is a chemical element with atomic number 3, which means it has 3 protons in its nucleus. The number of protons determines the atomic number and the positive charge of the nucleus. Electrons, on the other hand, carry a negative charge and orbit around the nucleus.

In a neutral lithium atom, the number of electrons is equal to the number of protons. Since lithium has 3 protons, it also has 3 electrons to balance the positive charge of the nucleus. Therefore, the statement that lithium atoms have a positive charge (А) is incorrect.

The size of an atom is determined by the electron cloud surrounding the nucleus. The nucleus itself is very small compared to the overall size of the atom. Therefore, the statement that the size of the nucleus is larger than the size of the atom (Г) is also incorrect.

To summarize, the correct statement about lithium atoms is that they do not have a negative charge (В).
