Sulphur has an atomic number 16 and a mass of 32.
State the number of protons and neutrons in the nucleus of sulphur. Give a simple diagram to show the arrangement of electrons in an atom of sulphur
Sulphur has an atomic number of 16, which means it has 16 protons in its nucleus. Since the atomic mass of sulphur is given as 32, and the atomic mass is the sum of protons and neutrons, we can subtract the atomic number (16) from the atomic mass (32) to find the number of neutrons.
Number of neutrons = Atomic mass - Atomic number
Number of neutrons = 32 - 16
Number of neutrons = 16
So, sulphur has 16 protons and 16 neutrons in its nucleus.
Simple electron arrangement diagram for an atom of sulphur:
Electrons are arranged in energy levels or electron shells around the nucleus of an atom. The first energy level can hold a maximum of 2 electrons, the second level can hold a maximum of 8 electrons, and the third level can hold a maximum of 8 electrons.
Sulphur has the electron configuration: 2, 8, 6
This means that in the first energy level, there are 2 electrons, in the second energy level, there are 8 electrons, and in the third energy level, there are 6 electrons.
how manny electrons does the average sulfur atom have?
The average sulfur atom has 16 electrons. This can be determined by looking at the atomic number of sulfur, which is 16. The atomic number represents the number of protons in the nucleus of an atom, and since atoms are neutral, they also have the same number of electrons.
A.) 2 other elements in the same period as Nitrogen (N) are ____ and ____
B.) 2 other elements in the same group as Nitrogen (N) are ____ and ____
A.) Two other elements in the same period as Nitrogen (N) are Oxygen (O) and Fluorine (F).
B.) Two other elements in the same group as Nitrogen (N) are Phosphorus (P) and Arsenic (As).
Oxygen has ____ valence electrons. To have a complete outer shell it will most likely (gain / lose) two electrons giving it a (+2 / -2) charge.
Oxygen has 6 valence electrons. To have a complete outer shell, it will most likely gain two electrons, giving it a -2 charge.

Li -
Ca -
B -
Se-
Li - Lithium has 1 valence electron.
Ca - Calcium has 2 valence electrons.
B - Boron has 3 valence electrons.
Se - Selenium has 6 valence electrons.
If Lithium and oxygen were placed together, predict what most of it would form and why?
1.) Lithium monoxide
2.) Lithium Oxide
3.) Lithium Peroxide
