Question

calculate number of electrons, protons and neutrons in 88sr38​

Answer 1

Answer:

Explanation:

The easiest way to find the number of protons, neutrons, and electrons for an element is to look at the element’s atomic number on the periodic table. That number is equal to the number of protons. The number of protons is equal to the number of electrons, unless there’s an ion superscript listed after the element.

Correct Question :

• Calculate the number of electrons, protons and neutrons in $\sf{{}^{88}_{38}Sr}$

Answer ::

The number of electrons, protons and neutrons of $\sf{{}^{88}_{38}Sr}$ is,

• The number of electrons = 38
• The number of protons = 38
• The number of neutrons = 50

Explanation :-

$\huge{\sf{{}^{88}_{38}Sr}}$

Here,

• 38 = Atomic number
• 88 = Mass number,

According the question,

As we know that,

Atomic number = Number of electrons = Number of protons,

Therefore,

➮ 38 = Number of electrons = Number of protons,

• The number of electrons = 38
• The number of protons = 38

Now, the number of neutrons are:

As we know that,

Mass number = Number of protons + Number of neutrons,

Therefore,

➮ Number of neutrons + 38 = 88

➮ Number of neutrons = 88 - 38

➮ Number of neutrons = 50

• The number of neutrons = 50

Things to remember:

• Atomic number = Number of electrons = Number of protons
• Mass number = Number of protons + Number of neutrons.
