How do you count the valence electrons of an atom?
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
How many valence electrons does ununhexium have?
116 protons and electrons Number of neutrons = Atomic mass of an isotope - Atomic number of the element; Uuq has many isotopes, each with a different number of neutrons.
Number of valence electrons in sodium?
Only 1, It's has 3 Energy Levels and only one Electron in it's outermost level.Sodium has 1 Valence Electrons. remember that in each group 1,2, 13, 14, 15, 16, 17, and 18 every element has the same Valence electrons in each group. Like Group 1 they all have 1 valence electrons. Group 2 has 2, Group 13 has 3, Group 14 all have 4, Group 15 all have 5, Group 16 all have 6, Group 17 all have 7, and finally Group 18 all have 8 valence electrons. the other groups have zero Valence electrons. Got to Touchspin on google and theres a periodic table that has the valence electrons for everything. On the side of the webpage its the second button that has the table.sodium has 8 valence electrons hint. the number of valence electrons is equal to the group number the element is in1,2, or 7 im not sureEdit: the answer is 1 electron in the valence shell, with a valence of 7Just like the rest of the alkali metals, sodium has one valence electron. This is why sodium is so reactive and has a low ionization energy--it is "eager" to get rid of this valence electron to fulfill the octet rule.See links/related questions below.Sodium has 1 valence election, just like all it's friends in the 1A group. Hope this helps!
What element has 2 shells and 3 valence electrons?
Oh, dude, that's like asking me to remember my high school chemistry class! The element you're looking for is aluminum. It's got 2 electron shells and 3 valence electrons hanging out, doing their thing. So yeah, aluminum is your guy for that question.
Which is more stable neutral chlorine atoms or chlorine ions Why?
Chlorine ion is more stable because it has got the maximum number(8) of electrons possible in its valence shell, it is known as the octet. When an ion achieves octet, it has got the electronic configuration of a noble gas, which is inert and very stable.
How many valence electrons does a nitrogen N atom have?
The atomic number for nitrogen is 7. Neutral nitrogen must have both 7 electrons and 7 protons then. The first 7 orbitals are filled as 1s2 2s2 2p3, which shows us that nitrogen has 5 valence electrons.
What is the total number of valence electrons for io2?
Well, honey, IO2 doesn't exist. But if you meant IO2-, then you've got yourself a total of 18 valence electrons. I hope that clears things up for you, darling.

How many electrons are in the outer energy level of a helium atom?
Helium and hydrogen and group 3 to 12 got 2 valence electron
Why do the elements belonging to a particular group exhibit similar chemical behavior?
Elements in the same group have the same number of valence electrons, which dictates their chemical behavior. Valence electrons are responsible for the way atoms interact with each other in chemical reactions. This similarity in valence electron configuration leads to similar chemical reactivity among group members.

How does helium differ from the other elements in its family noble gases?
Helium differs from other noble gases in its smaller atomic size and lower atomic mass. It is also the only noble gas that does not have a full shell of electrons, containing just 2 electrons in its outer shell. Additionally, helium is the least reactive of the noble gases due to its stable electron configuration.

What is the charge on the ion formed from the element Ga?
Gallium is +3 I had to find out the hard way. I just got it wrong on a chemistry test online. Ga3+ It tends to follow the trends of Al.
What is Lewis structure for hydrogen sulphide?
The Lewis structure for hydrogen sulfide (H2S) consists of two hydrogen atoms bonded to a central sulfur atom. Sulfur has 6 valence electrons, hydrogen has 1 valence electron each, totaling 8 valence electrons in the molecule. There are two lone pairs on the sulfur atom and the hydrogen atoms are bonded to the sulfur atom.
Why don't the noble gases have an electron affinity value?
Noble gases have a full valence shell of electrons, so they are stable and do not readily gain or lose electrons. This stability leads to very low electron affinity values for noble gases, as they do not have a strong tendency to attract additional electrons to achieve a more stable electron configuration.
