Argon, atomic number 18, since it is between chlorine and potassium on the Periodic Table of Elements.
What else can I help you with?
What element is in group 2 and has fewer protons than potassium?
The element in group 2 with fewer protons than potassium is beryllium. Beryllium has 4 protons in its nucleus whereas potassium has 19 protons. Both elements are found in group 2 of the periodic table.
What is more reactive silicon or chlorine?
Chlorine is more reactive than silicon. Chlorine readily reacts with a variety of elements and compounds to form chlorides, while silicon is less reactive and forms fewer compounds with other elements.
Which group 2 element has fewer protons than bromine but more protons than sulfur?
calciumThe element sulfur's atomic number is 16, so there are 16 protons in its nucleus. The element bromine's atomic number is 35, and there are 35 protons it its nucleus. This means the element will have an atomic number between 16 and 35. Since the question asked which Group 2 element fits in that window, we can go to the periodic table and look down the column of Group 2 elements and find that calcium is the element so described. It has the atomic number 20, and that means 20 protons in its nucleus.Remember that the Groups on the periodic table of elements are the vertical columns, and they range from Group 1 to Group 18. Group 2 elements are the so-called Alkaine Earth metals. A link is provided to the Wikipedia post on the periodic table. Bookmark this one, kids! Each element on the table is a hyperlink to the Wikipedia post on that element. Even the Group numbers are hyperlinks to the post on that Group! It just doesn't get any better that that.
Which one has fewer protons Nitrogen or Helium?
The periodic table is a good reference - check out the atomic number ! Helium - 2 protons, Nitrogen - 7 protons
How do two isotopes of an element are similar?
They have the same number of protons in the nucleus and same number of electrons surrounding the nucleus.
What element is in group 2 and has fewer protons than potassium?
The element in group 2 with fewer protons than potassium is beryllium. Beryllium has 4 protons in its nucleus whereas potassium has 19 protons. Both elements are found in group 2 of the periodic table.
This element has more valence electrons that oxygen fewer valence electrons than neon more protons than sodiumbut fewer protons than argon?
The element described is chlorine. It has 7 valence electrons, which is more than oxygen but fewer than neon. Chlorine has 17 protons, more than sodium but fewer than argon.
What have more protons than chlorine but less than potassium?
Elements that have more protons than chlorine (atomic number 17) but fewer than potassium (atomic number 19) are sulfur (atomic number 16) and argon (atomic number 18). Therefore, the only element that fits this criterion is argon, which has 18 protons.
What element has more valence electrons than S and Fewer protons than Ar?
Chlorine.
What element has more valence electrons than oxygen fewer valence electrons than neon more protons than soduim but fewer protons than argon?
Cl Chlorine
What element has more valence electrons than oxygen fewer valence electrons than neon more protons than sodium but fewer protons than argon?
The element described would be phosphorus. Phosphorus has 5 valence electrons (more than oxygen) and 15 protons (more than sodium but fewer than argon).
What element has more valence electrons that oxygen fewer valence electrons that neon more protons than sodium but fewer protons than argon?
there is no such element
What alkaline earth metal has fewer protons than bromine but more protons than sulfur?
potassium
What element has more valance electrons than oxygen fewer valance electrons than neon more protons than sodium but fewer prtons than argon?
The element that fits these criteria is sulfur. Sulfur has 6 valence electrons (more than oxygen with 6, fewer than neon with 8), 16 protons (more than sodium with 11, fewer than argon with 18).
Has 8 fewer protons than calacuim?
The element with 8 fewer protons than calcium is magnesium. Calcium has 20 protons, while magnesium has 12 protons.
Element that has more valence electrons than oxygen fewer valence electrons than neon more protons than sodium but fewer protons than argon?
The element in question is magnesium. It has 12 protons (more than sodium and less than argon), 2 more valence electrons than oxygen (which has 6), and 8 fewer valence electrons than neon (which has a full valence shell with 8 electrons).
What element in group 16 has more protons than sodium but fewer protons than argon?
The element in group 16 with more protons than sodium but fewer protons than argon is sulfur (S). Sodium has 11 protons, sulfur has 16 protons, and argon has 18 protons.
