What element has more valence electrons in oxygen fewer valence electrons than neon more protons than sodium but fewer protons than argon?
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.
Which element has more valence electrons?
group 18
d. Elements with the most valence electrons are in group 18.
How many valence electrons does oxygen have?
six valence electrons
Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen’s valence electrons as 2s²2p⁴.
Does neon have full valence electrons?
Neon, with its configuration ending in s2p6, has eight valence electrons.
What is the valence electron for NE?
[He]2s²2p⁶
Neon/Electron configuration
Which is the most abundant metal with 3 valence electrons?
Group 3A contains the metalloid boron, the well known metal aluminium, and three less familiar metals (gallium, indium, and thallium) All these elements have three valence electrons. Aluminium is the most abundant metal in Earth’s crust. It is often combined with oxygen in a mineral called bauxite.
What are the valence electrons of Group 6A?
Group 6A has three nonmetals (Oxygen, sulfur, and selenium), and two metalloids (tellurium and polonium). 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.
How many valence electrons does helium have in it?
Helium has two valence electrons. Each of the Noble Gases has eight valence electrons. The noble gases are colorless and odorless and extremely unreactive.
Which is higher in melting point magnesium or sodium?
The melting point of magnesium is 650 degrees celsius, which is much higher than the melting point of sodium- 98 degrees celsius. Differences in reactivity among the alkaline earth metals are shown by the ways they react with water. Calcium, strontium, and barium react easily with cold water.
