Which of these is not true about the proton

a. protons exist within the nuclei of atoms

b. electrons surrounding atoms get pulled into the nucleus by protons

Option (B).

Explanation:

Atoms consist three subatomic particles that are electron, proton and neutron. Electrons participates in the formation of ions and has the ability to gain or lose the electrons.

Electron revolves around the nucleus whereas protons and neutrons are present inside the nucleus. Protons are positively charged and their number can not be changed inside the atom. Protons does not have the ability to push the electrons. Electron revolve in the fixed orbit and cannot fall down in the nucleus.

Thus, the correct answer is option (B).

in 1972 the fluid—mosaic membrane model of membrane structure was proposed based on thermodynamic principals of organization of membrane lipids and proteins and available evidence of asymmetry and lateral mobility within the membrane matrix [s. j. singer and g. l. nicolson, science 175 (1972) 720–731].

i think the answer is gold im not entirely sure
