What element has more valence electrons than oxygen fewer valence electrons than neon?
Nickel (Ni) 18. This element has an atomic number that is double the atomic number of silicon. 19. This element has more valence electrons than oxygen, fewer valence electrons than neon, more protons than 18 sodium, but fewer protons than argon.
How many valence electrons does oxygen have?
six valence
So oxygen has six valence, valence electrons.
Does potassium have more electrons than neon?
Yes, it has atomic number of 19 representing 19 electrons, more than neon with only 10 electrons.
Does carbon have more valence electrons than oxygen?
Oxygen has the atomic number 8 and carbon has the atomic number 6. So the number of valence electrons is the number of electrons in the outermost orbital. For oxygen it is 6 while for carbon it is 4.
How many valence electrons are in neon?
eight valence electrons
Neon, with its configuration ending in s2p6, has eight valence electrons.
Does hydrogen have more electrons than neon?
It has fewer electrons than neon and can react with electron donors. Each hydrogen has 2 valence electrons, the same as helium. Carbon has 8 valence electrons in the product, the same as neon.
Which element has the least amount of valence electrons?
Sodium (Na)
Sodium (Na) with atomic number 11 has the least number of valence electrons. The total number of electrons present in the outer shell of atom are called Valence electrons.
How many protons neutrons and valence electrons does oxygen have?
Oxygen is the 8th element in the periodic table. This means that oxygen has 8 protons and 8 electrons. In order to get the number of neutrons you take the atomic weight in this case 15.9999~16 and you subtract it by the number of protons (16-8). To get the number of valence electrons just look at the numbers above the oxygen on the periodic table.
Which of the following elements has six valence electrons?
All these elements have six valence electrons. Oxygen is the most abundant element in Earth’s crust. Group 7A are called Halogens and they have seven valence electrons. Fluorine and chlorine are gases, bromine is a liquid that evaporates quickly, and iodine is a solid that sublimes.
How many valence electrons does oxygen have in Group 6?
Since oxygen is in group 6 it means that it has 6 valence electrons. This means that oxygen has 8 protons and 8 electrons.
What are the similarities between halogens and gases?
Fluorine and chlorine are gases, bromine is a liquid that evaporates quickly, and iodine is a solid that sublimes. Despite their physical differences, the halogens have similar chemical properties. Group 8A are called Noble Gases. Helium has two valence electrons. Each of the Noble Gases has eight valence electrons.
