Boron is a only non metal in group 13 elements.
It is a Metaliod
no
Sodium is a metal (an alkali metal).
The boron symbol "B" comes from the first two letters of the element's name, boron. It was derived from the Arabic word "buraq," which means borax or an oxide of boron.
Boron has two orbital shells. The first shell contains 2 electrons, while the second shell can hold up to 8 electrons. Boron typically has 5 electrons, with 2 in the first shell and 3 in the second shell.
Across a row on the periodic table ionization energy increases. Down a column, ionization energy decreases. --------------------------------------------------------- The first Ionization energy of Boron is 800.6 kJ mol-1
The element that contains the first p electron is boron, which has an atomic number of 5. Boron's electron configuration is 1s2 2s2 2p1, meaning that the first p electron is found in the 2p orbital.
I warn you: it's not very exciting. Boron was named after the mineral borax.
It's a metal. More information about it is available on its page on wikipedia.

Sir Humphrey Davy isolated boron in 1808. The first to realize it was an element was probably John Jakob Berzelius. Boron compounds had been known for thousands of years.
