Frequently Asked Questions

Why does boron have 6 neutrons?

Why does boron have 6 neutrons? We are given that boron-10 had five protons in its nucleus, and any element always has the same number of protons in its nucleus (atomic number). For boron-11 this total is 11, and five of the particles are protons, thus 11−5=6 neutrons.

What does atomic mass tell us about the atom?

What does the atomic mass tell us about an atom of an element? The mass number tells us the number (the sum of nucleons) of protons and neutrons in the nucleus of an atom. It is traditionally represented by the symbol Z. The atomic number uniquely identifies a chemical element.

How many protons and neutrons does boron have?

Explanation: Boron has actually 5 protons, 5 neutrons and also 5 electrons. The atomic number (also recognized as the proton number) the Boron is 5 together it has 5 protons.

What is the group number of boron?

The boron group are the chemical elements in group 13 of the periodic table, comprising boron (B), aluminium (Al), gallium (Ga), indium (In), thallium (Tl), and perhaps also the chemically uncharacterized nihonium (Nh). The elements in the boron group are characterized by having three valence electrons.
