Anatom of an element has no electron,will that atom have any mass or not? Can antom exist

Chemistry
1 answer:
densk [106]2 years ago
5 0

Answer:

<em>Generally, all atoms of elements contain three sub-atomic particles- </em><em>Protons</em><em>(Positively-charged), </em><em>Neutrons</em><em>(Neutral) and </em><em>Electrons</em><em>(Negatively-charged)</em><em>. </em>

<em>The Magnitude of the Positive Charge possessed by the Protons and the Magnitude of the Negative Charge possessed by the Electrons cancel each other, which make the atom electrically neutral. </em>

<em>Hence,</em>

<em>Without any electrons, the magnitude of the positive and negative charges wouldn't balance, and the atom would be unstable and disintegrate almost immediately. Hence, all stable atoms should have electrons revolving around them, where the number of protons and electrons are the same, under normal conditions.</em>

<em>To Conclude,</em>

<em>Every atom of an element will have electrons arranged in different shells, or matter couldn't exist without electrons.</em>

1.5 moles of Al is how many<br> atoms?
aev [14]

Answer:

<h2>9.03 × 10²³ atoms </h2>

Explanation:

The number of atoms of Al can be found by using the formula

<h3>N = n × L</h3>

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

N = 1.5 × 6.02 × 10²³

We have the final answer as

<h3>9.03 × 10²³ atoms</h3>

Hope this helps you

What is the ph of a solution of 0.400 m k2hpo4, potassium hydrogen phosphate?
dusya [7]
When we can get Pka for K2HPO4 =6.86 so we can determine the Ka :

when Pka = - ㏒ Ka

          6.86 = -㏒ Ka 

∴Ka = 1.38 x 10^-7

by using ICE table:

               H2PO4- →  H+  + HPO4
initial      0.4 m            0         0

change     -X                +X       +X

Equ       (0.4-X)               X          X

when Ka = [H+][HPO4] / [H2PO4-]

by substitution:

1.38 X 10^-7 = X^2 / (0.4-X)   by solving for X

∴X = 2.3x 10^-4 

∴[H+] = X = 2.3 x 10^-4

∴PH = -㏒[H+]

        = -㏒ (2.3 x 10^-4)
 ∴PH  =  3.6
