Increasing order (lowest first) for the values of e/m (charge/mass) for electron (e). Proton (p). neutron (n) and α particle is n, α, p, e. Any particle’s electrical charge is represented by the letter “e.” “m” stands for the particle’s mass.

### What is e/m Ratio?

The charge of an electron to mass of an electron ratio is known as the “e/m” ratio. The electron (e), proton (p), neutron (n), and alpha () particle’s e and m magnitudes are listed below:

 Mass in kg Mass in terms of u Charge in Coulomb e- 9.109 × 10-31 kg 1 / 1837 u -1.602176 × 10-19 C p- 1.6726219 × 10-27 kg 1 u + 1.602176 × 10-19 C n- 1.674927471×10-27 kg 1 u 0 alpha- 6.644 657 3357 x 10-27 kg 4 u Double of proton
• Electron- charge is -1 if we compare it with a proton. Mass is 1 / 1837 u. So, the e/m ratio is 1837.
• Proton – charge of the proton is +1, mass is 1 u. So, the e/m ratio = 1/1 = 1.
• The neutron has no charge. 1 u is the mass. Consequently, e/m ratio = 0/1 = 0.
• Alpha particle with a mass of 4 u and a charge of 2. The e/m ratio is therefore 2/4 = 0.5.
• By comparing these, we see that the neutron, alpha, proton, and electron have rising e/m ratios.
• As a result, the values of e/m (charge/mass) for electrons are listed in increasing order (lowest first) (e). proton(p). n, p, e, and neutron (n) are the particles.

Summary:

## Increasing order (lowest first) for the values of e/m (charge/mass) for electron (e). proton (p). neutron (n) and α particle is? (1) e, p, n, α (2) n, p, e, α (3) n, p, α, e (4) n, α, p, e

Ordering the values of e/m (charge/mass) for electrons in decreasing order (lowest to highest) (e). Proton (p). n, p, e, and neutron (n) are the particles. After comparing all of these, we can get charge/mass ratio.
