<span>A compound is a substance composed of two or more elements that are chemically combined in a fixed proportion. A molecule must be nonpolar if the molecule has a symmetrical charge distribution. A molecule must be nonpolar if the molecule has a symmetrical charge distribution. An electrolytic cell differs from a voltaic cell because an electrolytic cell requires an outside energy source for a nonspontaneous chemical reaction to occur. As electrons push each other around, the electron orbital clouds form different shapes. Scientists propose that atoms can have up to seven principle energy levels of electrons around the nucleus. This orbital diagram for nitrogen shows how electrons fill the sub-orbitals. Wave Mechanical .This is the electron configuration for the element sulfur, which has 16 electrons. We and everything around us are made of tiny groups of particles, called atoms. While atoms were once thought to be the smallest unit of matter, they are actually made up of much tinier, high-energy, negatively-charged particles circling at a crazy pace around a nucleus of positive and neutral particles. Since the outer-shell (valence) electrons control the chemical properties of a material, it would be useful to understand how they behave.</span>

Why is it necessary to adjust the height of the graduated cylinder when measuring the volume of CO2 (g) produced? What type of e
kolezko [41]

Explanation:

This process ensures that the pressure inside of the graduated cylinder is the same as the atmospheric pressure in the room.

Suppose the level of water inside and outside the cylinder is same, pressure stays the same. Therefore, total pressure of the is made equal to atmospheric pressure by adjusting the height of cylinder. it is done till the water level is equal.

Which of the following would form an anion? He H N B
vagabundo [1.1K]
<h3><u>Answer;</u></h3>

Nitrogen (N)

<h3><u>Explanation;</u></h3>
  • Atoms may lose or gain electrons to achieve stability. Metal atoms lose electrons to attain stable configuration, and as a result they form positively charged ions called cations.
  • <u>Non-metals on the other hand gain electrons to attain stable configuration, and as a result form negatively charged ions called anions.</u>
  • <u>Among the elements given above nitrogen (N) gains electrons to form a negatively charged ion called anion. </u>
