Answer:

The maximum number of energy sublevels found in any energy level at ground state is one

Explanation:

The energy state in general can be specified by four quantum numbers:

1) n = principal quantum number = 1,2,3...

2) l = angular momentum where l = 0...n-1

where: l = 0 corresponds the 's' sublevel

l = 1, corresponds to the 'p'

l = 2, corresponds to the 'd' sublevel

3) m = magnetic quantum number which extends from -l....+l

4) s = spin = +1/2 or -1/2

For the ground state n = 1 and l = 0 which corresponds to a single 's' sublevel.

1. Explain how groups 1A-8A in the periodic table are organized by their number of valence electrons.
nirvana33 [79]

Explanation:

1. Explain how groups 1A-8A in the periodic table are organized by their number of valence electrons.

The valence electrons in an atom are the outermost shell electrons. They are the most loosely held electrons in an atom.

Coincidentally, the periodic table of elements divided into vertical groups and horizontal periods can be said to be arranged according to the number of valence electrons.

  • Atomic numbers are used to arrange elements on the periodic table.
  • Down a group, the number of electronic shell increases. More electrons are added to new energy levels.
  • As we move from left to right across a period, the number of electrons in elements increases but electronic shell is the same.
  • Down a group electronic shell increases but the number of valence electrons are the same.
  • All elements in Group 1A has just one valence electrons, Group 2A has two valence electrons.........Group 8A has eight valence electrons.
  • Moving across groups is synonymous to moving from left to right on the periodic table.
  • Due to this trend, the periodic table is arranged based on the number of valence electrons.

3. explain how you know the number of valence electrons for each group.

The number of valence electrons in a group is the group number:

   Group      Number                     valence electrons

              1A                                                 1

              2A                                                2

              3A                                                 3

              4A                                                 4

               5A                                                5

               6A                                                6

               7A                                                7

               8A                                                8

You want to know how many moles of gas your lungs can hold. You start off with a balloon that has 1.4 moles of gas and occupies
Mrrafil [7]

Number of moles : n₂ = 1.775 moles

<h3>Further explanation</h3>

Given

Moles = n₁ = 1.4

Volume = V₁=22.4 L

V₂=28.4 L

Required

Moles-n₂

Solution

Avogadro's hypothesis, at the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles  

The ratio of gas volume will be equal to the ratio of gas moles

\tt \dfrac{V_1}{V_2}=\dfrac{n_1}{n_2}

Input the values :

n₂ = (V₂ x n₁)/V₁

n₂ = (28.4 x 1.4)/22.4

n₂ = 1.775 moles

What happens when liquid magma is cooled
Vaselesa [24]
Magma that cools quickly forms one kind of igneous rock, and magma that cools slowly forms another kind. When magma rise from deep within the earth and explodes out of a volcano, it is called lava, and it cools quickly on the surface. Rock formed in this way is called extrusive igneous rock.

What mass (in grams) of silver contains the same number of atoms as 5.59 grams of sulfur?
Amanda [17]

Answer:

18.84 g of silver.

Explanation:

We'll begin by calculating the number atoms present in 5.59 g of sulphur. This can be obtained as follow:

From Avogadro's hypothesis,

1 mole of sulphur contains 6.02×10²³ atoms.

1 mole of sulphur = 32 g

Thus,

32 g of sulphur contains 6.02×10²³ atoms.

Therefore, 5.59 g of sulphur will contain = (5.59 × 6.02×10²³) / 32 = 1.05×10²³ atoms.

From the calculations made above, 5.59 g of sulphur contains 1.05×10²³ atoms.

Finally, we shall determine the mass of silver that contains 1.05×10²³ atoms.

This is illustrated below:

1 mole of silver = 6.02×10²³ atoms.

1 mole of silver = 108 g

108 g of silver contains 6.02×10²³ atoms.

Therefore, Xg of silver will contain 1.05×10²³ atoms i.e

Xg of silver = (108 × 1.05×10²³)/6.02×10²³

Xg of silver = 18.84 g

Thus, 18.84 g of silver contains the same number of atoms (i.e 1.05×10²³ atoms) as 5.59 g of sulfur
