What energy level are carbon's valence electrons?
Two valence electrons at second s- and p-level each: 2s2 2p2 The other two are nonvalence electrons on 1st s-level: 1s2
Do a family of elements share the same number of valence electrons?
Yes they do. Groups/Families tell the number of valence electrons (the number of electrons in the outermost energy level).
What do you notice about the number of valence electrons as you move from left to right across a periodic table example Na-Ar?
each time, an energy level is added. ;3
How many electrons are in the outermost or valence energy level for C?
An easy way to determine how many valence electrons an atom has is by looking at the periodic table. The first two columns on the left of the periodic table and the last six on the right are the elements which have valence electrons. Each column represents 1 valence electron. So column one has one valence, column two has two valence. Only counting the first 2 and the last 6 six columns, Carbon is is column four, which means it has four valence electrons.
How many valence electrons each noble gas has?
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2 valence electrons) and have stable electronic configuration.
Each energy level of an atom has a maximum number called?
valence electrons
What energy level are carbon's valence electrons?
Two valence electrons at second s- and p-level each: 2s2 2p2 The other two are nonvalence electrons on 1st s-level: 1s2
What does a atom's outermost electron shell does?
The outer energy level is in the electron cloud surrounding the nucleus. Each ring that surrounds the nucleus is an energy level and contains a different number of electrons.
How many electrons can the outer level of an atom hold?
an atom has different energy orbitals: s, p, d, and f. each orbital can hold two electrons. the outside energy or highest energy levels of electrons is called the valence shell or valence electrons. for an atom to be stable it wants the electron configuration for the valence shell to be "s2, p6." to answer your question the outer level of an atom can hold 8 electrons. it is called the valence shell.
What kind of elements have the same number of valence electrons?
Valence electrons are the electrons in the outer energy level. Each period shares many similar characteristics, one of which being the amount of electrons in the outer energy level. If you are unfamiliar, the Periods are the Vertical Columns, and Families are the Rows. I hope this helps you.
How many electrons are on the seconed level of argon?
There are 8 electrons on the second energy level of argon. Every element in Group 1 on the period tables have 1 valence electron. In group 2, 2 valence electrons. Then it skips to 13 (remember it by forgetting the 1st digit). In group 13, there are 3 valence electrons. 14 - 4 valence, 15 - 5 valence, 16 - 6 valence, 17 - 7 valence, 18 - 8 valence. Argon is in Group 18. It has 8 valence electrons and since it is in period 3, it has 3 electron energy levels. Since the noble gases are stable, that means no electrons are in the excited state. So there can't be more or less than 8 electrons in the second energy level. Because there are 4 available orbitals in the 2nd energy level (1 s sublevel orbital and 3 p sublevel orbitals), that means that all orbitals are filled (2 electrons to each orbital) and there are 8 electrons in all in the 2nd energy level of Argon. I'm a chemistry student also. Chemistry is awesome.
How many electrons is there in the outer most energy level?
For Hydrogen and Helium, the valence band [1S] holds two electrons. For the next series of the periodic table, eight electrons fill the two valence bands, 1S and 3P (two each equals 8).
Which electrons in oxygen have more energy those in the first energy level or in the second?
More energy have the electrons in the second level of energy.
Do a family of elements share the same number of valence electrons?
Yes they do. Groups/Families tell the number of valence electrons (the number of electrons in the outermost energy level).
How many electrons can each level hold?
Maximum of 2n2, where n is the energy level.

Maximum number of electrons in each energy level?
