how we can find the atomic mass of any elements​

Answer 1

Answer:

we have to remember it no way to find it

Answer 2

Question:

How to find the Atomic Mass of any Element?  

Answer:

• To find the mass of one atom of associate element, we'd like to feature( add )  up the mass of protons and neutrons . Atomic mass of the associate atom of the element is Mass of Protons + Mass of Neutrons

• Atomic mass of an atom of an element  = ${m_p+m_n$

• Where $m_p$ is the mass of the protons of the element and $m_n$ is the mass of neutrons

For example :

Example 1 :

Lets take the Element Sodium. It has the symbol Na and has the atomic number as 11 and has 12 neutrons

Number of protons = Atomic Number = 11 protons

Atomic Mass = Mass of Protons + Mass of Neutrons

$=m_p+m_n$

$=11+12$

$=23$

Therefore Sodium has an atomic mass of 23

Example 2 :

Lets take the Element Argon. It has the symbol Ar and has the atomic number as 18 and has 22 neutrons

Number of protons = Atomic Number = 11 protons

Atomic Mass = Mass of Protons + Mass of Neutrons

$=m_p+m_n$

$=18+22$

$=40$

Therefore Argon has an atomic mass of 23

Information about Electrons , Protons and Neutrons:

• Atoms are fabricated from extraordinarily small particles referred to as protons, neutrons, and electrons.

• Protons and neutrons are within the center of the atom, creating up the nucleus.

• Electrons surround / Move around the nucleus.

• Protons have a charge which is positive .

• Electrons have a charge which is negative .

• The charge on the nucleon and electron are precisely the same size however opposite.

• Neutrons don't have any charge.

• Since opposite charges attract, protons and electrons attract every other.
