What mode of radioactive decay is most likely for the na-20 isotope?

Nuclear reaction: ²⁰Na → ²⁰Ne + e⁺(positron) + ve(electron neutrino).
Beta decay is radioactive decay in which a beta ray and a neutrino are emitted from an atomic nucleus.
There are two types of beta decay: beta minus and beta plus. 

In beta plus decay, a proton is converted to a neutron and positron and an electron neutrino, so mass number does not change.

In beta minus decay, neutron is converted to a proton and an electron and an electron antineutrino.

odds are decent that your handwriting right now looks a little bit different than it did five years ago, and will look different again in five more. when i look back through my notebooks from middle school to now, i see a long, slow progression from meticulous and teeny letters to bigger, sloppier ones, plus a few side detours: sometime in high school, for example, i decided those loopy cursive lowercase f’s were just the coolest, adopting them as the lone rep for cursive in my otherwise all-print handwriting.
