When atoms lose or gain electrons in chemical reactions they form?

The chemical name for a compound with the formula Ba3N2 is barium nitride.

Barium nitride is composed of the element barium (Ba) and the element nitrogen (N). The subscript "3" indicates that there are three barium atoms, and the subscript "2" indicates that there are two nitrogen atoms in the compound.

The naming of ionic compounds, such as barium nitride, follows a specific pattern. The name of the cation (positively charged ion) is stated first, followed by the name of the anion (negatively charged ion).

Thus, the name "barium nitride" accurately describes the composition of the compound Ba3N2, indicating that it consists of three barium atoms and two nitrogen atoms bonded together.

The mass of Mg consumed is approximately 26.28 g.

The balanced chemical equation for the reaction between magnesium (Mg) and nitrogen ([tex]\rm N_2[/tex]) to produce magnesium nitride ([tex]\rm Mg_3N_2[/tex]) is:

[tex]\rm \[3 \text{Mg} + \text{N}_2 \rightarrow \text{Mg}_3\text{N}_2\][/tex]

Given:

Mass of [tex]\rm N_2[/tex] = 10.1 g

Molar mass of [tex]\rm N_2[/tex] = 28.02 g/mol (molar mass of nitrogen)

Using stoichiometry, we can determine the moles of [tex]\rm N_2[/tex]:

Moles of [tex]\rm N_2[/tex] = Mass / Molar mass = 10.1 g / 28.02 g/mol ≈ 0.3602 mol

From the balanced equation, we see that 3 moles of Mg react with 1 mole of [tex]\rm N_2[/tex] to produce 1 mole of [tex]\rm Mg_3N_2[/tex].

Therefore, the moles of Mg consumed are: Moles of Mg = 3 * Moles of [tex]\rm N_2[/tex] = 3 * 0.3602 mol = 1.0806 mol

The molar mass of Mg is 24.31 g/mol (molar mass of magnesium), so the mass of Mg consumed is:

Mass of Mg = Moles of Mg * Molar mass = 1.0806 mol * 24.31 g/mol ≈ 26.28 g

Therefore, the mass of Mg consumed is approximately 26.28 g.

In this reaction, 3 mg of magnesium reacts with nitrogen gas to produce magnesium nitride. The mass of Mg consumed is 26.3 g.

In the given reaction, 3 mg of magnesium reacts with nitrogen gas (N2) to produce magnesium nitride (Mg3N2). To determine the mass of Mg consumed, we need to calculate the molar mass of Mg and the molar ratio between Mg and N2. The molar mass of Mg is 24.31 g/mol. Since the balanced equation shows a 3:1 ratio between Mg and N2, we divide the mass of N2 (10.1 g) by the molar mass of N2 (28.01 g/mol) to get the moles of N2 and then multiply that by the molar ratio to find the moles of Mg consumed. Finally, we multiply the moles of Mg consumed by the molar mass of Mg to get the mass consumed.

Calculation:
Mass of N2 = 10.1 g
Molar mass of N2 = 28.01 g/mol
Moles of N2 = (mass of N2) / (molar mass of N2) = 10.1 g / 28.01 g/mol = 0.3608 mol
Moles of Mg consumed = (moles of N2) x (molar ratio) = 0.3608 mol x 3/1 = 1.0824 mol
Mass consumed = (moles of Mg consumed) x (molar mass of Mg) = 1.0824 mol x 24.31 g/mol = 26.3 g

Graph of First Ionization Energy (kJ/mol) on the y-axis and Atomic Number on the x-axis is attached below.

3. Analysis:

The graph of ionic radius versus atomic number for Group 2A elements will show a decreasing trend as atomic number increases.

This is because, as you move down the group, the number of electron shells increases, leading to a greater distance between the outer electrons and the nucleus, resulting in a larger ionic radius.

On the other hand, the graph of first ionization energy versus atomic number will show an increasing trend. This is because, as you move down the group, the outermost electrons are further away from the nucleus, experiencing weaker attractive forces, thus requiring more energy to remove them, resulting in higher ionization energies.

These relationships align with the periodic trends studied, where atomic size increases down a group, leading to decreasing ionization energy.

Final answer:

The atomic number on the periodic table indicates the number of protons in the nucleus of an atom of that element, defining its identity. This number is usually found at the top of the element's square on the table, allowing for easy identification and distinction between elements.

Explanation:

The atomic number on the periodic table tells you the number of protons found in the nucleus of the atom of that element. Each element on the periodic table has a unique atomic number, which is usually displayed at the top of the element's square.

This number is crucial because it defines the identity of the element; for instance, hydrogen has an atomic number of 1, meaning all hydrogen atoms have 1 proton in their nucleus. Similarly, helium has an atomic number of 2, indicating that every helium atom has exactly 2 protons in its nucleus.

The periodic table arranges elements in increasing atomic number, and this is the characteristic that makes each element unique compared to all others.

By looking at the periodic table, you can determine the atomic number of an element, and thus know how many protons its atoms contain. This makes the periodic table an indispensable tool for scientists and students alike.

Nucleosynthesis is the stellar process in which the fusion of hydrogen produces other elements, such as helium. This process occurs through the proton-proton chain reaction in stars like the Sun.

The stellar process in which the fusion of hydrogen produces other elements is called nucleosynthesis. During nucleosynthesis, hydrogen nuclei (protons) combine to form helium nuclei in a process known as the proton-proton chain reaction. This is an important example of nuclear fusion that occurs in the Sun and other stars, and it is responsible for the production of energy and the creation of heavier elements.

Answer:

The ionization energy of each successive element generally decreases

Explanation:

The ionization energy increases in the periods of the periodic table and decreases in the groups. If the atom is very small, we will need a lot of energy to release the electron, while if the atom is larger the energy will be greater.

As the atomic radius increases, the ionization energy of the elements ; ( A )

As we move across the periods in the periodic table ,the ionization energy of the elements increases relatively, while as we go down the Groups in the periodic table the atomic radius increases while the ionization energy decreases as well.

Therefore the elements of group 1 on the periodic table will experience a decrease in ionization energy as we go down the group.

Hence we can conclude that as the atomic radius increases, the ionization energy of the elements will decreases.
