The elements in group 7A have one valence electron true or false?

∙ 11y ago
A valence electron, or valence electrons, are found in all of the elements. A valence electron is an electron located on the out most shell of an element (the valence shell). Most elements will have more than one valence electron. Oxygen, or O, has six valence electrons because its outer shell consists of six electrons.

Why do the elements belonging to a particular group exhibit similar chemical behavior?
The electron configurations of the elements in each main group are regular and consistent:the elements in each group have the same number of valence electrons.
What elements have 5 electrons in their electron dot diagrams?
The elements that have 5 electrons in the dot diagram means that they have 5 valence electrons. These elements are found in group 5A. Elements include, nitrogen, phosphorus, arsenic, antimony, and bismuth.
How do you determine the valence electrons using the orbital diagram?
Group 1 - 1 valence electron Group 2 - 2 valence electrons Group 13 - 3 valence electrons Group 14 - 4 valence electrons Group 15 - 5 valence electrons Group 16 - 6 valence electrons Group 17 - 7 valence electrons Group 18 - 8 valence electrons Groups 3 - 12 technically have 2 valence electrons, but will also use d sublevel electrons as valence electrons as well. So their number of valence electrons vary (even for the same element) and require some memorization.
How many valence electrons in H2 atom?
H2 is not an atom, it is a diatomic molecule. Each hydrogen atom has 1 valence electron. When two hydrogen atoms covalently bond to form an H2 molecule, there are two valence electrons being shared by the two atoms.
Atoms of elements with the same electron configuration are organized in in the Periodic Table?
They are not! It is a prevalent myth that the elements are organized so that elements with the same configuration are organized into the same group, but all that really matters is the number of valence electrons, and that much is guaranteed by the arrangement in order of atomic number.So we have for example in group 10, Ni with configuration [Ar] 3d8 4s2 , Pd with configuration [Kr] 4d10 , and Pt with configuration [Xe] 4f14 5d9 6s1.Group 4 is characterized (supposedly) by the electron configuration d2 s2 but thorium which has this configuration is not placed in this group but in the actinides.
What is the number of valence electrons for the elements in group 1?
The elements in Group 1 have one valence electron in their outermost s orbital.
What is the name of the group of elements with two valence electron in each period?
The name of the group of elements with two valence electron in each atom is "alkaline earth metals."
What is the number of valence electrons in group one?
Valence electrons are the electrons in the furthest electron shell from the nucleus.For the first three rows, essentially, the number of valence electrons is the number of squares the element is away from the beginning of the row at the left.For example. Sodium is the first (group 1) it has 1 valence electron. Magnesium is the second, it has 2 valence electrons.
What is the number of valence electron for all the elements in periodic table group 1A 1?
One valence electron.
Elements within a group have similar number of?
electron valence hh
What is the general valence shell configuration for the elements in group 7A?
Valence electron configuration in group 7A (halogens): ns2, np5 in which n=2, 3, 4, 5, ... etc. Starting with fluorine, F, electron configuration: (1s2), 2s2 2p5 (non valence electrons in () brackets)
How do you determine the number of valence electrons if you know the group no of elements?
valence electrons are electrons at the outermost shell as we all know, group in PE can be determined by looking at the valence electron thus if it is in group 1..then the valence electron is 1
The atoms of the elements in Group 2 have the same?
number of valence electron
Why are elements in group one of the periodic table cations?
The elements of group 1 has 1 valence electron. They lose 1 electron to form cation.
Group 1a elements have how many electrons in their valence shells?
All these have one electron in their valence shell.
What is the electronic structure of group 1 elements?
An outer electron shell with only one electron.
What elements only have 1 valence electron?
All the atoms in group 1.
