Boron is one position to the left of carbon on the periodic table. the atomic number of carbon is 6. given its position on the periodic table, what is the atomic number of boron

Answer is: the atomic number of boron (B) is 5.

Atomic number is the number of protons, which is characteristic of a chemical element. Atomic number increases from left to right in Periodic table.

Boron is an element with atomic number 5, which means it has 5 protons and 5 electrons, boron atom has neutral charge.

Electron configuration of boron: ₅B: 1s² 2s² 2p¹, it has three valence electrons in 2s and 2p orbitals.
