An atom has 18 protons, 18 electrons, and 20 neutrons. This atom has _____.

Lera25 [3.4K]

an atom that has 18 protons, 18 neutrons and 20 neutrons. This atom has mass number of 38

mass number is calculated as number of protons + number on neutrons

therefore the mass number of the atom = 18+20= 38

Since the atom has a electronic configuration of 2.8.8,the atom cannot be negatively or positively charged because it is stable.

The atomic number of the atom is 18 since atomic number is equal to number of protons

Explanation:

A smokestack, is a very tall channel commonly used in many instances to release gases produced by combustion processes directly into the air. These high towers are aimed at dispersing the gaseous pollutants over a wider area thereby minimizing their impact.

Old and inefficient smokestack do not contaminate the soil since they are very high towers that discharge gases directly into the atmosphere. Hence they are not part of the sources of soil contamination in abandoned mines.
