Part 1: Name Two Elements That Have The Same Properties As Potassium (K). (4 Points)Part 2: Determine

Answers

Answer 1

Answer:

Part 1: Sodium and Rubidium.

Part 2:

Protons = 12

reason: protons are equal to the atomic number of an atom. For Magnesium, atomic number is 12.

Neutrons:

[tex] = { \tt{24 - 12 }} \\ = { \tt{12 \: neutrons}}[/tex]

reason: neutrons is given by formula:

[tex]{ \tt{neutrons = mass \: number - atomic \: number}}[/tex]

where mass number of magnesium is 24.

electrons: = 12 electrons

reason: Magnesium atom has electrons summing up to 12

Answer 2

part 1: hydrogen and sodium? my memory is so bad ngl

part 2: 36 because there are 12 protons, 12 electrons, and 12 neutrons in an atom of magnesium.

What is quartz?

Quartz is a hard crystalline mineral found within the Earth's crust and which is composed mainly of the mineral silica. Silica is mostly silicon(iv) oxide.

Quartz is colourless and its crystalline structure is of a hexagonal prism. The atoms are arranged in a regular repeating grid to form the hexagonal crystal.

Therefore, it is can be concluded that quartz is an extended structure that is made of repeating patterns of atoms.
