Part 1 Name two elements that have the same properties as potassium K 4 points Part 2 Determine the number of protons electrons and neutrons present in an atom class=

Respuesta :

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
