Is Within a family on the periodic table the number of electrons on the valence level is always the same true of false?
The elements in each column of the Periodic Table have the same number of valence electrons. None of the other characteristics listed in the question is common to all these elements.
What else can I help you with?
Why does the middle part of the periodic table doesn't have any valency?
Because the highest level of electron orbitals inhabited by the elements in the middle of the periodic table are not the farthest away from the nucleus, so their valence electrons are always present.
What is the common between all the elements in the same column in the periodic table?
Elements that are contained within the same column in the periodic table are known as a group. All of the elements in the first group of the table have one electron in their outer shell.
Does each Transition Metal on the Periodic Table only have 2 valence electrons according to the electron configuration with subshells?
Because valence electron are always in the outer most layer (here the N number). You would think that the valence would come from the D orbital but if you look attentively, there will always be a S orbital with a higher N number. Example: Sc 1s2 2s2 2p6 3s2 3p6 4s2 3d1 The valence electron will always come from the 4s2 subshell, and as you go along the period, the electrons are going to add up only in the 3d orbital.
How valence electrons can atoms of nonmetals have?
always more than 4
Which two orbitals could the valence electrons be in?
Valence electrons can be found in the s and p orbitals in an atom. The s orbital can hold a maximum of 2 electrons, while the p orbitals can hold a maximum of 6 electrons. This arrangement allows for a maximum of 8 valence electrons in an atom.
Element within a group always have the same number of?
Elements within a group always have the same number of valence electrons.
Is the number of valence electrons equal to the number of protons?
No, the number of valence electrons is not always equal to the number of protons. The number of valence electrons is determined by the group number of an element on the periodic table, while the number of protons is the atomic number of the element.
How many electrons does aluminum with an atomic number of 13 have in its valence shell?
None. the positive charges on the 13 protons and the negative charges on the 13 electrons cancel each other out
How many valence electrons does Sulfur?
there are 6 electrons in valence shell of sulphur so it accepts two electrons to complete the octet (8 electrons in last shell) so its valency in ionic compounds is always - 2.
Why does the middle part of the periodic table doesn't have any valency?
Because the highest level of electron orbitals inhabited by the elements in the middle of the periodic table are not the farthest away from the nucleus, so their valence electrons are always present.
Why does the octet rule not always refer to a stable arrangement of 8 valence electrons?
The octet rule does not always refer to a stable arrangement of 8 valence electrons because some atoms can accommodate more than 8 electrons in their valence shell (expanded octet), such as elements in Period 3 and beyond in the periodic table. Additionally, some molecules, like radicals or species with an odd number of electrons, may not satisfy the octet rule but can still be stable due to resonance or other factors.
Is an atoms number of protons is always the same as its number of valence electrons?
For neutral atoms, the electron number is always the same as the proton number.For ions, charged atoms, the proton number is different than the electron number by the charge (e.g. a hydrogen ion, H(+1) has 1 proton and 0 electrons, 1 more proton than electrons).
Are valence shell electrons always in the same energy level?
No
What is the common between all the elements in the same column in the periodic table?
Elements that are contained within the same column in the periodic table are known as a group. All of the elements in the first group of the table have one electron in their outer shell.

Because valence electron are always in the outer most layer (here the N number).

Example: Sc 1s2 2s2 2p6 3s2 3p6 4s2 3d1 The valence electron will always come from the 4s2 subshell, and as you go along the period, the electrons are going to add up only in the 3d orbital.
Which elements is less reactive an element whose atoms have seven valence electrons or an element whose atoms have eight valence electrons?
the element with seven valence electrons will be more reactive. The reason for this is that elements want to always want to have a full valence shell (they always want 8, like a noble gas). The element with eight valence electron is happy with its full shell and will not want to get rid of any electrons.
How valence electrons can atoms of nonmetals have?
always more than 4
