Each isotope of Oxygen has a different number of neutrons

<h3>Further explanation </h3>

The elements in nature have several types of isotopes

Atomic mass is the average atomic mass of all its isotopes

Isotopes are atoms has the same number of protons but has a different number of neutrons.

So Isotopes are elements that have the same Atomic Number (Proton)

Some of the isotopes of oxygen are:

$\tt _8^{16}O,_8^{17}O,_8^{18}O$

Each isotope has 8 protons and 8 electrons but has a different number of neutrons

For O-16: number of neutrons = 16-8 = 8

For O-17: number of neutrons = 17-8 = 9

For O-18: number of neutrons = 18-8 = 10

Mumz [18]

The answer is A

The bacteria that cause disease are known as pathogens. The term pathogen is used to refer to all types of disease causing microorganisms. These include bacteria, fungi, protozoa and fungi.

Bacteria. Microscopic organisms that come in many shapes and sizes. Some bacteria that cause disease in man are Salmonella typhi which causes typhoid and Streptococcus pyogens which causes sore throat.

Virus. A virus is a microscopic entity much smaller than even bacteria and can only exist inside a host such as a cell. It cannot live on its own. Some viruses that cause disease are HIV which causes AIDS and Rhino virus which causes colds.

Fungi. These are a group of unicellular or multicellular microscopic organisms that live by feeding on organic matter. A type of fungus that causes disease is Trichophyton mentagrophyte which is responsible for athlete's foot.

Protozoa. A group of one celled organisms which live in water. Entamoeba histolytica is a protozoa, an amoeba which causes amoebic dysentery in man.

The complete orbital notation diagram of an atom is shown. Five squares are shown aligned horizontally. Inside the first square

Jlenok [28]

Answer:

l = 0, 1, and 2; it is in a d orbital.

Explanation:

1. Angular momentum quantum number

One square means l = 0.

Three squares mean l = 1.

Five squares mean l = 2.

If an atom contains electrons with l = 2, it must also have electrons with l = 0 and 1.

Thus, the electrons in the atom can be assigned the angular momentum quantum numbers l = 0, 1, and 2.

Those in a set of five squares all have l = 2.

2. Location of electron

The last electron is the lone electron in the fifth square. Since l = 2, the electron is in a d orbital.
