A neutral atom of sulfur has the following characteristics:
Paraphin [41]

Answer: proton number = 16

Electron number =16

Neutron number =16

Explanation: Mass number = 32

Atomic number = 16

atomic number = proton number = 16.

Since the atom is neutral, proton number is the same as electron number i.e Electron number = proton number =16

Mass number = proton + Neutron

32 = 16 + Neutron

Neutron = 32 — 16 = 16

When an atom of lithium loses an electron, the atom becomes a
Radda [10]
An electron has a negative charge. When an atom loses an electron, it becomes a positive ion.
When an atom of lithium loses an electron and becomes an ion, it has one less electron shell, so its radius is smaller than the radius of the atom.
The answer is 3.

Write the atomic symbol for the isotope of bismuth with 125 neutrons.
vlada-n [284]

First, isotopes <u>are the atoms of a single element whose nuclei have a different number of neutrons</u>, and therefore, differ in mass numbers. You should know that atoms are formed by a nucleus that has a small size and is made up of protons and neutrons. The nucleus is surrounded by a cloud of electrons, which are found in a region of the atom called the cortex.

The mass number, represented as A, <u>is the sum of the number of protons and neutrons in the nucleus</u>. On the other hand, the atomic number (Z) is <u>the number of protons that exist in the nucleus. </u>

The isotopes of an element X are represented as follows,

<em>(see first attached picture)</em>

It should be noted that the number of neutrons of a chemical element can be calculated as the difference A-Z.

<u>The atomic and mass numbers of bismuth with 125 neutrons are</u>:

Z = 83

A = 83 + 125 = 208

Thus, the atomic symbol of the bismuth isotope with 125 neutrons is:

<em>(see second attached picture)</em>
