Matching the Number of Constituents to the Nucleide

To match the number of constituents to the nucleide, we need to identify the nucleide based on the given information. Let's analyze the provided data:

1. 70 electrons 2. 57 protons 3. 57 neutrons 4. 70 nucleons

To determine the nucleide, we need to understand the composition of an atom. An atom consists of protons, neutrons, and electrons. Protons and neutrons are collectively known as nucleons.

The number of protons determines the atomic number of an element, while the sum of protons and neutrons gives the atomic mass number. Electrons orbit the nucleus and are equal in number to the protons in a neutral atom.

Based on the given information, we can conclude the following matches:

1. 70 electrons: A Neon (Ne). Neon has an atomic number of 10, which means it has 10 protons and 10 electrons [[1]]. 2. 57 protons: D Lanthanum (La). Lanthanum has an atomic number of 57, which means it has 57 protons [[2]]. 3. 57 neutrons: C Lanthanum (La). The atomic mass of Lanthanum is approximately 139.9, which means it has 57 neutrons (139.9 - 57 = 82.9, which is close to 83) [[2]]. 4. 70 nucleons: B Gallium (Ga). Gallium has an atomic mass of approximately 69.7, which means it has 70 nucleons (protons + neutrons) (69.7 - 31 = 38.7, which is close to 39) [[3]].

Therefore, the matches are as follows:

1. 70 electrons: A Neon (Ne) 2. 57 protons: D Lanthanum (La) 3. 57 neutrons: C Lanthanum (La) 4. 70 nucleons: B Gallium (Ga)
