It is not possible to say for certain which pair of the isotopes below are of the same element as no options have been provided. There are many different pairs of isotopes that make up many different elements.
There are 3 pairs of valence electrons present on the boron atom in BF3. Boron has 3 valence electrons, and each fluorine atom provides one additional electron, giving a total of 6 valence electrons on boron.
To draw Lewis dot structures for elements, determine the total number of valence electrons for the element. Then, place the electrons around the element symbol in pairs, following the octet rule (except for hydrogen and helium, which follow the duet rule). Remember to show all valence electrons and distribute them evenly around the element symbol.
N and As for two. They all have 5 valence electrons (as do Sb and Bi).
There are 4 valence electrons on the oxygen atom in the water molecule. Oxygen has 6 valence electrons, and in a water molecule, oxygen forms 2 covalent bonds with the hydrogen atoms, sharing 2 of its valence electrons with each hydrogen atom.
The pairs of valence electrons that do not participate in bonding in a diatomic oxygen molecule are called lone pairs. These pairs of electrons are not involved in forming the double bond between the oxygen atoms in O2.
The answer is not 6 as said here before! The number of valence electrons in O2 (oxygen molecule) is: 12 valence electrons. 6 of them from each oxygen (O) atom. 4 valence electrons make up the double bond between the two oxygen atoms, and the remaining 8 valence electrons form lone pairs (non-bonding pairs) on the oxygen atoms, 2 lone pairs on each. I hope there is some help in this.
True. Nitrogen can share three pairs of electrons and has a lone pair of electrons for a total of eight in it's valence shell
There are 3 pairs of valence electrons present on the boron atom in BF3. Boron has 3 valence electrons, and each fluorine atom provides one additional electron, giving a total of 6 valence electrons on boron.
A I ion, specifically iodide (I⁻), has a total of 8 valence electrons. In its neutral state, iodine has 7 valence electrons, but it gains one additional electron when it forms an ion, resulting in 8. Since each pair of valence electrons consists of 2 electrons, there are 4 pairs of valence electrons in an iodide ion.

These would be the elements in group 16. The elements in group 16 have six valence electrons. Those valence electrons are represented in a Lewis diagram by surrounding them with six dots. When drawing a diagram for an element with six valence electrons, there should be two pairs of dots (four total), and two separate dots.

Valence numbers, in relation to the periodic table, mean electrons. If you know the basics of chemistry, you know that electrons form pairs in the "shells" of an atom. The valence number refers to the number of electrons in the outermost "shell".
six, read your periodic table and look at the electron configurations. the last number is how many electrons are in the valence orbital. the number of electrons in that valence orbital and how many valence electrons there are in that atom. oxygen has a 2-6 configuration, hence six valence electrons. lewis dot diagram has a capital O surrounded by three pairs of dots (six total), chemistry is easy and fun for everyone.Oxygen has 6 valence electrons.
If an atom has five valence electrons, it will have one lone pair of electrons.
