How many electrons are shared in a double bond?

In a double bond, a total of four electrons are shared. These electrons are shared between two atoms that are bonded together by two pairs of electrons.

How many electrons are shared in a double bond?

1) 6 electrons
2) 1 electron
3) 4 atoms
4) 2 electrons

The correct answer is 4) 2 electrons.

In a double bond, two pairs of electrons are shared between two atoms. Each pair of electrons consists of two electrons, so in total, four electrons are shared in a double bond.

In a double bond, a total of four electrons are shared. Each atom contributes two electrons to form the bond.

In a double bond, four electrons are shared between two atoms. This is because a double bond consists of two pairs of electrons. To determine the number of electrons shared in a double bond, you need to know the number of valence electrons for each atom involved and how many are needed for a stable arrangement.

Here's a step-by-step guide to finding the number of electrons shared in a double bond:

1. Determine the number of valence electrons for each atom: Valence electrons are the electrons located in the outermost energy level of an atom. You can find the number of valence electrons by referring to the periodic table. For example, carbon (C) has four valence electrons.

2. Determine the number of electrons needed for a stable arrangement: Most atoms strive to achieve a full outer shell of electrons, referred to as the octet rule. This means they need eight valence electrons, with the exception of hydrogen (which only needs two). Carbon needs four more electrons to complete its outer shell.

3. Calculate the number of shared electrons in the double bond: In a double bond, two pairs of electrons are shared between two atoms. Since each pair consists of two electrons, multiplying two by two gives us four shared electrons.

So, in a double bond, four electrons are shared between two atoms to achieve a stable electron arrangement.
