how to determine the aspects for core and valence electrons in a periodic table. How comes in some elements like cobalt the 3d i
dusya [7]

Answer:

See explanation

Explanation:

The electron configuration of an atom in an element determines the property of the atom. The core electrons are found inside the atom while the valence electrons are found on the outermost shell of the atom.

For cobalt, the outermost shell electron configuration is; [Ar] 3d7 4s2. The 3d7 and 4s2 are found in the valence shell of cobalt.

For arsenic, the electronic configuration is [Ar] 3d¹⁰ 4s² 4p³. The valence electrons are 4s2, 4p3. The 3d electrons are found inside the arsenic atom.

A large container holds 2 liters of water. 45.0 grams of NaCl is added to the container. What is the molarity of sodium chloride
djverab [1.8K]

Answer:

THE MOLARITY OF SODIUM CHLORIDE IN THE CONTAINER IS 0.3846 M.

Explanation:

Molarity of a solution is the number of moles of solute per dm3  of solution.

Mass concentration = Molar concentration * Molar mass

1. calculate the mass concentration;

Mass conc. = 45 g in 2 L

= 45 g in 2 dm3

In 1 dm3, the mass will be 45 / 2

= 22.5 g/dm3 of NaCl.

2. Calculate the molar mass;

(Na = 23, Cl = 35.5)

Molar mass = ( 23 + 35.5 ) g/mol

Molar mass = 58.5 g/mol

3. calculate the molarity

Molarity = mss concentration / molar mass

Molarity = 22.5 g/dm3 / 58.5 g/mol

Molarity = 0.3846 mol/dm3 of NaCl.

The molarity of sodium chloride in the container is 0.3846 mol/dm3

Which of the following correctly describes the difference (on average) between an electron in a 2s orbital and an electron in a
bulgar [2K]

Answer:

C: electrons is the 3s orbital are higher than those in the 2s orbital

Explanation:

Looking at the options, the correct one is that the electrons in the 3s orbital will possess more energy than those in the 2s orbital. This is because the the 2s orbitals will be filled with electrons first before the 3s orbital.

Also from basics we know that the energy of an orbital increases as the quantum number increases.
