The possible ψ for the last-filled electron in a magnesium ion is ψ 2,0,−1. Hence, the correct choice is C.

Generally, the electrons present in an atom are located in a system of atomic orbitals around the nucleus. The position of each electron is often controlled by a set of four quantum numbers. The electron configuration usually describes the distribution of all electrons present in the atom via shells and subshells. Shells are defined as the principal energy levels and subshells are the orbital types located at each shell, some of which may appear multiple times. Basically the electron configuration of a neutral atom is often derived from its element's position in the periodic table, which can then be modified to derive the electron configuration of a simple cation/anion.

The electronic configuration for magnesium ion is,

Mg²⁺ = 1s² 2s² 2p⁶

Answer:

approximately equal to 152 grams of uranium

Explanation:

1. to find the number of atoms in 25.0 grams of potassium, we can find the number of moles of potassium in 25.0 g by dividing that by the molar mass (found on a standard IUPAC periodic table) and then multiply that by Avogadro's constant, the number of 'items' (molecules, atoms, ions, etc...), which is 6.022×10²³ to get the number of atoms in 25.0 g of potassium.

n(K) = m/M = 25.0/39.10 = 0.639386... mol of potassium.

N(K) = n×Nₐ = 0.639386...×6.022×10²³ = 3.85038...×10²³ atoms

2. In uranium, 3.85038...×10²³ atoms also equals 0.639386... moles. We can multiply this number by the molar mass of uranium (grams per mole), to get the mass of uranium.

m(U) = nM = 0.639386...×238.0 = 152.1738...

Therefore, the mass of uranium which contains the same number of atoms as 25.0 g of potassium ≈ 152 g

Explanation:

d orbit contain 10 electrons .

Potassium atom is weakly electronegative and would be more stable if it gave up a valence electron.

The propensity of an element to draw a pair of bonding electrons is measured by its electronegativity. The Pauling measure is most frequently employed. The number ranges from 4.0 for fluorine, the most electronegative element, to 0.7 for cesium and francium, the least electronegative elements.

What happens if two elements with equivalent electronegativity combine?

Think about the connection between elements A and B. Since both atoms have the same propensity to attract the bonding pair of electrons if they are equally electronegative, it will typically be located halfway between the two atoms.

Normally, A and B would have to be the same atom to form a connection like this. This kind of bond can be found in compounds like H2 or Cl2, for instance. It's essential to keep in mind that this is a typical image. Actually, the electrons are in a molecule orbital, where they are constantly revolving. The electrons in this type of connection are distributed equally between the two atoms, making it a "pure" covalent bond.

The amount of hydrogen gas that  is produced from 50g of Mg and 75g Hcl is: 2.08 grams of hydrogen gas is produced from 50 grams of Mg and 75 grams of HCl.

To determine how much hydrogen gas is produced from 50g of Mg and 75g of HCl, we need to use the stoichiometry of the balanced chemical equation:

Mg + 2HCl → MgCl2 + H2

First, let's calculate the number of moles of Mg and HCl:

Number of moles of Mg = 50 g / 24.31 g/mol = 2.06 mol

Number of moles of HCl = 75 g / 36.46 g/mol = 2.06 mol

The mole ratio of Mg to H2 is 1:1, so the number of moles of H2 produced is also 2.06 mol.

Finally, we can use the molar mass of hydrogen (1.008 g/mol) to convert the moles of H2 to grams:

Mass of H2 produced = 2.06 mol × 1 mol/1 mol × 1.008 g/mol = 2.08 g

Therefore, 2.08 grams of hydrogen gas is produced from 50 grams of Mg and 75 grams of HCl.

Answer:

To solve this problem, we need to use the balanced chemical equation and the molar mass of Cu and Ag to determine the amount of Cu that reacted and the amount of Ag produced.

The balanced chemical equation is:

Cu + 2AgNO3 → Cu(NO3)2 + 2Ag

From the equation, we can see that 1 mole of Cu reacts with 2 moles of Ag to produce 1 mole of Cu(NO3)2 and 2 moles of Ag. This means that the ratio of Cu to Ag in the reaction is 1:2.

To find the amount of Cu that reacted, we can use the ratio of Cu to Ag and the mass of Ag produced:

Molar mass of Cu = 63.55 g/mol

Molar mass of Ag = 107.87 g/mol

Mass of Ag produced = 89.5 g

Number of moles of Ag produced = mass / molar mass = 89.5 g / 107.87 g/mol = 0.829 mol

Since the ratio of Cu to Ag is 1:2, the number of moles of Cu that reacted is half the number of moles of Ag produced:

Number of moles of Cu = 0.829 mol / 2 = 0.4145 mol

To find the mass of Cu that reacted, we can use the number of moles of Cu and the molar mass of Cu:

Mass of Cu reacted = number of moles of Cu × molar mass of Cu = 0.4145 mol × 63.55 g/mol = 26.32 g

Therefore, 26.32 grams of Cu reacted in the reaction.

The volume of the balloon at the top of the mountain can be calculated using Boyle's Law, which states that the pressure and volume of a gas are inversely proportional at a constant temperature.

The formula for Boyle's Law is P1V1 = P2V2, where P1 is the initial pressure, V1 is the initial volume, P2 is the final pressure, and V2 is the final volume.
We are given the initial pressure (P1) as 101.3 kilopascals, the initial volume (V1) as 2.15 litres, and the final pressure (P2) as 83.1 kilopascals. We need to find the final volume (V2).
Plugging the given values into the formula, we get:
101.3 kPa × 2.15 L = 83.1 kPa × V2
Rearranging the equation to solve for V2, we get:
V2 = (101.3 kPa × 2.15 L) / 83.1 kPa
V2 = 217.795 L / 83.1 kPa
V2 = 2.62 L
Therefore, the volume of the balloon at the top of the mountain is 2.62 litres.

Moles (symbol: mol) is a unit of measurement that is commonly used in chemistry to express the amount of a substance. One mole is defined as the amount of a substance that contains as many elementary entities (such as atoms, molecules, or ions) as there are in 12 grams of carbon-12. The number of elementary entities in one mole is known as Avogadro's number, which is approximately 6.022 x 10^23. This means that one mole of any substance contains 6.022 x 10^23 elementary entities. The concept of moles is important in chemistry because it allows us to easily compare and relate the amount of different substances in chemical reactions. For example, if we know the number of moles of a reactant and the stoichiometry of a reaction, we can calculate the number of moles of product that will be produced. This makes it possible to predict and control the outcome of chemical reactions.
