How many valence electrons does indium have?
The electron configuration shows that the last shell of indium has three electrons. Therefore, the valence electrons of indium are three.
How many electrons does indium have?
49 electrons Indium has 49 electrons, with an electronic configuration of (Kr)4d105s25p1. In compounds, indium most commonly donates the three outermost electrons to become indium(III), In3+.
Does indium have 2 valence electrons?
(b) In: indium has three valence electrons and all the rest are core electrons.
Does indium have 5 valence electrons?
(Note: Group 13 is also called group 3A). So, as the indium element is present in group 13, it has 3 valence electrons.
How do you determine valence electrons?
For neutral atoms, the number of valence electrons is equal to the atom's main group number. The main group number for an element can be found from its column on the periodic table. For example, carbon is in group 4 and has 4 valence electrons. Oxygen is in group 6 and has 6 valence electrons.
Which are the 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. Created by Sal Khan.
What is the valency of indium?
three electrons With only three electrons in its valency shell, indium is an electron acceptor and is used to dope pure germanium and silicon; it forms stable indium(I), indium(II), and indium(III) compounds. The element was discovered in 1863 by Ferdinand Reich (1799–1882) and Hieronymus Richter (1824–90).

What are the 7 valence electrons?
The family of elements having seven electrons in the valence shell is halogens, i.e., chlorine, fluorine, bromine, iodine, astatine.
How many valence electrons are in each atom?
As a general rule, a main-group element (except hydrogen or helium) tends to react to form a s2p6 electron configuration. This tendency is called the octet rule, because each bonded atom has 8 valence electrons including shared electrons.
How do you calculate valence?
The ones digit in the group number is the number of valence electrons. To solve without a periodic table, find the electron configuration of the element and count the electrons into 1 group of 2, and then into shells of 8. The number in the last group is the amount of valence electrons.
How do you know the valence electrons of an element?
Explanation: The periodic table contains rows and columns. To find how many valence electrons are in an element, simply locate the column number that it is in, and that determines the number of valence electrons in an element. This rule works only for elements excluding the transition metals.
How many electrons are in each ring for indium?

What element has the valence of 7?
Any element in the halogen group will have seven valence electrons. These elements include fluorine, chlorine, bromine, iodine, and astatine.
How many valence electrons does be?
The electron configuration of beryllium shows that the last shell of beryllium has two electrons. Therefore, the valence electrons of beryllium are two.
What is the easiest way to find valency?
The valency of an atom is equal to the number of electrons in the outer shell if that number is four or less. Otherwise, the valency is equal to eight minus the number of electrons in the outer shell. Once you know the number of valence electrons, you can easily calculate the valency. Was this answer helpful?
How many valence electrons does each element have?
According to this rule, group 1 elements have one valence electron, group 2 elements have two valence electrons, group 13 elements have three valence electrons, group 14 elements have four valence electrons, and so on.

How many valence electrons are in the periodic table?
An atom with one or two valence electrons more than a closed shell is highly reactive, because the extra valence electrons are easily removed to form a positive ion….The number of valence electrons.

How do you count valence electrons?
For neutral atoms, the number of valence electrons is equal to the atom's main group number. The main group number for an element can be found from its column on the periodic table. For example, carbon is in group 4 and has 4 valence electrons. Oxygen is in group 6 and has 6 valence electrons.
Which group of elements has 8 valence electrons?
group 18 Any element in group 18 has eight valence electrons (except for helium, which has a total of just two electrons). Examples include neon (Ne), argon (Ar), and krypton (Kr).

What elements has 6 valence electrons?
They are oxygen (O) , sulfur (S) , selenium (Se) , tellurium (Te) , and polonium (Po) . Note that the synthetic element livermorium (element number 116 ) is also predicted to have six valence electrons, but it's not proven yet. These elements all belong in group 16 or the chalcogens group.
