How many electrons in an atom can have each of the following quantum number or sublevel designations?
lutik1710 [3]

Answer: a:6 electrons, b:10electrons, c: 2electrons

Explanation:

1.Principle quantum number(n)

n is the number of shell, it is a positive integer. The maximum number of electrons in a shell is 2(n2)

2.Azimuthal quantum number(l)

l is the number of subshell in the principal shell

The name of subshell are s, p, d, f

The number of nodes in each subshell is

s is l=0, p is l=1, d is l=2, f is l=3.

Each shell can have 2 x l + 1 sublevels, and each sublevel can accommodate maximum of 2 electrons and have two electrons.

A. n=2, l=1 then 2 x 1 + 1= 3 subshell, 3*2= 6 electrons in the p subshell

b. 3d, d is l = 2 then 2 x 2 + 1 = 5 sublevels, 5*2=10 electrons in the d subshell

c. 4s, s is l=0 then 2 x 0 + 1 = 1 sublevel, 1*2=2 electrons in the s subshell.

How will you recognize that a single replacement reaction has occured when you combine an active metal with 6m hcl?
frez [133]

A single replacement or displacement reaction occurs when one ingredient in a compound replaces another. Only another metal can replace a less active one; a metal can only displace another metal, and a non-metal can only displace another non-metal.

<h3>Displacement reaction:</h3>

The tendency of the element to lose electrons is what makes it metallic. Due to their bigger sizes and propensity to lose electrons as size, the number of shells, and nuclear force of attraction rise, the most active metals are found on the left side of the periodic table.

The reaction in which the more reactive element displaces the less reactive element is known as the displacement reaction.

When we combine an active metal with HCl, the reaction is as follows:

We are taking sodium, Na which is the most active metal. It will replace H in HCl because it is more reactive than H.

                       2Na + 2HCl → 2NaCl + H₂

Three ways to recognize if a single displacement reaction has taken place:

1. Color change

2. Formation of bubbles (a gas)

3. Formation of a precipitate
