According to brownsted Lowry theory and acid is a substance that donates(or loses) protons but then why are metals considered as basic although they give up electrons which is similar to give up proton

Explanation:
According to bronsted Lowry theory, an acid is a substance that donates protons (H⁺), but metals considered as basic because metal gives H⁻.
Suppose we take an acid HCl and Other metal Hydride NaH.
Then, Here Chlorine withdraw e⁻ from H and a positive charge will appear on H.
And Sodium is Electropostive element and Hydrogen is Electronegative. So, Here negative charge will appear on H.
Chemical equation -
It's true that sodium (Na) donates e⁻ but in chemical reactions sodium can't be taken alone. It should be taken in the form of compound.
Here, we take Sodium Hydride.
It's the reason that metals are considered as basic.

And Sodium is Electropostive element and Hydrogen is Electronegative. So, Here negative charge will appear on H.
Chemical equation -
H⁺Cl⁻ + Na⁺H⁻ → Na⁺Cl ⁻ + H⁺H⁻ (H₂↑)
