Elements with the most valence electrons are in group 18 . 4.
Which element has greater number of valence electrons?
Elements with the most valence electrons are in group 18 . 4.
Which element has the highest Valency?
As it belongs to the VI Periodic Table group, Sulphur has six valence electrons. It thus has maximum valency.
What elements has 4 valence electrons?
Carbon has four valence electrons and here a valence of four.
What element in Period 2 has 7 valence electrons?
| Chemical element | 7 | N | Nitrogen | Block | p-block | Electron configuration | [He] 2s 2 2p 3 |

What is the valency of gold?
As we can see that the valence shell of the gold atom is 6 and there is 1electron in this valence shell, so it can lose this electron to form a +1 oxidation state, therefore, having a valency 1.
Does tin have 4 valence electrons?
Tin is located in the group 14 of the periodic table, which means that it has four electrons in its outermost shell, i.e. four valence electrons .
How do we find 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.
Does Silicon have four valence electrons?
In the second shell, it has eight electrons. -In the outermost shell that is the third shell it has four electrons. -Valence electrons are electrons of the outermost shell which can participate in chemical bonding. ... -As in silicon, four electrons are present in the outermost shell, so silicon has Four valence electrons.
What element in Period 2 has 3 valence electrons?
How many valence electrons does boron have? You must recognize that the second principal energy level consists of both the 2 s and the 2 p sublevels and so the answer is three.
What is the element in Period 2 with 5 valence electrons?
The s and p orbitals of arsenic have 2 and 3 electrons respectively making 5 valence electrons.
Which is the group with Valency zero?
Group $18$ elements have zero valency because the outermost shell of these electrons are complete and form a stable electronic configuration. They are non reactive elements. These elements are also known as noble gases . The elements are helium, neon, argon, krypton, xenon and radon.
