Lithium - 3
Oxygen is smaller than lithium because oxygen has fewer electrons and protons compared to lithium, resulting in a smaller atomic size. Additionally, oxygen has a higher effective nuclear charge, which pulls the electrons closer to the nucleus, making the atom smaller.
The element with 8 fewer protons than calcium is magnesium. Calcium has 20 protons, while magnesium has 12 protons.
Lithium.
Calcium. Calcium has 20 protons, sulfur has 16, and bromine has 35.
Argon, atomic number 18, since it is between chlorine and potassium on the Periodic Table of Elements.
No, an atom of gold has more protons than an atom of oxygen. Gold has 79 protons, while oxygen has 8 protons.
Lithium has the lowest number of protons of any metal: 3. Hydrogen an helium have fewer protons bu they are not metals.
there is no such element
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.
LI ; lithium is an example with 3 protons.
Cl Chlorine
The element described would be phosphorus. Phosphorus has 5 valence electrons (more than oxygen) and 15 protons (more than sodium but fewer than argon).
