<span>In polar coordinates, the origin is called the pole. Polar coordinate system is actually a two dimensional coordinate system. In this type of system the reference point is known by the name of pole. I hope that this is the answer that you were looking for and the answer has come to your desired help.</span>
Copper(II) oxide or cupric oxide is the inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu2O or cuprous oxide. As a mineral, it is known as tenorite. It is a product of copper mining and the precursor to many other copper-containing products and chemical compounds
Answer:
- Option <u><em>d) isotope</em></u>.
Explanation:
All atoms of a same element have equal number of protons (atomic number) but <em>may</em> <em>differ in the number of neutrons.</em>
<em />
The atoms that differ in the number of neutrons are named<em> isotopes</em>.
For example: carbon-12 and carbon-13 are diferent isotopes of the same element, carbon. They have the same number of protons (6, which is the atomic number of carbon). On the other hand, while carbon-12 has 6 neutrons, carbon-13 has 7 neutrons.
As per the other choices:
- a) <em>anions</em> are ions with negative charges: atoms (or group of atoms) that have gained one or more electrons.
- b) <em>cations</em> are ions with positive charge: atoms (or group of atoms) that have lost one or more electrons.
- e) <em>atoms</em> are the individual minimum parts of an element that preserves the properties of such element. All atoms of the same element have the same number of protons and have, essentially, the same chemical properties.
