How many valence electrons does an element in group 4 have are they reactive?
All elements in group four have FOUR valence electrons. This is easy to remember because the group number located at the top of the periodic table of elements corresponds precisely in all cases to the experimentally observed number of valence electrons in the elements. It is also important to know that the elements in group eight (the inert gases) all have eight valence electrons, meaning that they can neither gain or lose electrons in the way of bonding with other elements, thus the maximum number of valence electrons any molecule can have is eight.
How many valence electrons are present in silcon?
Silicon has 4 valence electrons.
How many valence electrons does H2Se have?
H2Se has six valence electrons. Each hydrogen contributes one valence electron, and selenium contributes four.
A carbon atom can bond with four other atoms because it has what valence electrons?
A carbon atom can bond with four other atoms because it has four valence electrons in its outer shell, allowing it to form stable covalent bonds by sharing electrons with other atoms to complete its octet.
What number of valence electrons that carbon has?
Neutral Carbon atoms contain 6 electrons and 6 protons 2 electrons are found in the 1st electron ring and 4 in the outer ring to reach a stable electron (8 in the outershell) arrangement carbon requires 4 covalent bonds to be formed
Which elements contain four valence electrons?
Elements in Group 14 (Carbon family) contain four valence electrons. These elements include carbon, silicon, germanium, tin, and lead.
How can you tell from an element's number of valence elns whether the element is more likely to form a caor an anion?
If an element has less than four valence electrons, it will tend to lose its valence electrons and form cations. If an element has more than four valence electrons, it will tend to gain electrons and form anions. An element that has four valence electrons will tend to form covalent bonds rather than ionic bonds.

Which atoms are most reactive?
The most reactive elements have either 1 valence electron or 7 valence electrons
How many valence does a carbon atom have?
Carbon has four valence electrons. Each of theseelectrons can pair with an electron from another atom to form a strong covalent bond. In carbon, all the electrons with the principal quantum number 2 are valence electrons, but the two electrons with principal quantum number 1 are not.
How many valence electrons does silica have?
4
What is the number of electrons needed for stability in the groups of the periodic table?
They r noble gases which have stable valance shell and grotp no. 18
How many electrons does carbon share to complete its valence shell?
Carbon typically shares 4 electrons to complete its valence shell, forming covalent bonds with other atoms. Carbon has 4 valence electrons, so by sharing these electrons with other atoms, it can achieve a full octet and become more stable.
What is the number of valence electrons for Sn?
Sn has 50 total electrons and is in the Group 4a elements on the periodic table. The nearest Noble Gas that is before Sn is Kr, which has 36 electrons. Therefore, the number of inner electrons (the same as Kr's electrons) is 36, outer electrons is 4 and valence is 4 as well (because its a Group 4a
Which group has four valence electrons?
Group 4 elements in the periodic table have four valence electrons. This includes elements like carbon (C), silicon (Si), germanium (Ge), tin (Sn), and lead (Pb).
What is the number electrons in the valence shell in carbon?
There are four valence electrons because it is in 4A row. 5A 5 valence 6A 6 valence etc. Carbon has four.
How many valence electrons are present in silcon?
Silicon has 4 valence electrons.
