The correct answer is Be+
That is because it lost a single electron but still has the same number of protons, and thus the effective charge attracting each electron is greater, which in turn makes the radius even smaller
Answer:
Explanation:
the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat.

The ratio of effusion rates for nitrogen and neon is calculated by use of the Grahams law formula
that is rate of N2/ rate of Ne = square root of mm of Ne/mm or N2
=square root of 20.18/28 = 0.849
