Yes. Cesium has 55 protons while radon has 86.
The element with 8 fewer protons than calcium is magnesium. Calcium has 20 protons, while magnesium has 12 protons.
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.
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.
The element that fits this description is silver. Silver is part of Group 11 and is known for its shiny appearance, malleability, and excellent conductivity of heat and electricity. It has an atomic number higher than cesium and lower than radon.
Cl Chlorine
there is no such element
potassium
This would be Sb - Antimony.
Thorium: 90 protons Uranium: 92 protons
The element described would be phosphorus. Phosphorus has 5 valence electrons (more than oxygen) and 15 protons (more than sodium but fewer than argon).
Argon, atomic number 18, since it is between chlorine and potassium on the Periodic Table of Elements.
Yes. If it has fewer electrons that protons, it will be a positively charged ion, and if it has more electrons than protons, it will be a negatively charged ion.
