Question

1) This element has more than 50 but less than 75 protons and it is in Group 17.
2)This element has more electrons than oxygen but fewer electrons than neon.
3)This element has an atomic number lower than that of aluminun but an atomic mass that is greater than sodium.
4)This Group 2 element has fewer protons than bromine but more protons than sulfur.
5)This element has an atomic number that is one greater than platinum.

Answer 1

1) This element has more than 50 but less than 75 protons and it is in Group 17............IODINE (I)
2)This element has more electrons than oxygen but fewer electrons than neon........FLUORINE (F)
3)This element has an atomic number lower than that of aluminun but an atomic mass that is greater than sodium........MAGNESIUM (Mg)
4)This Group 2 element has fewer protons than bromine but more protons than sulfur..........CALCIUM (Ca)
5)This element has an atomic number that is one greater than platinum.............GOLD/AURUM (Au)

Answer 2

A chemical element, popularly known as an element, is any substance that can be broken into simple molecules by ordinary chemical reactions, further calculation can be defined as follows:

• This element belongs to Group 17 IODINE and contains more than 50 but less than 75 protons (I).
• The element contains more electrons than oxygen yet fewer electrons as neon FLUORINE (F).
• The element has a lower atomic number than aluminum yet a higher atomic weight than sodium MAGNESIUM (Mg).
• The Group 2 element contains fewer protons than bromine but much more protons as sulfur CALCIUM (Ca).
• Each element does have an atomic number one higher than platinum GOLD/AURUM (Au).

Therefore, the final answer is "Iodine, Fluorine, Magnesium, Calcium, and Gold".
