I think that's B, the symbol for the element boron.
Boron has 5 protons and 5 electrons.
The most common isotope has 6 neutrons.
The other main isotope has only 5 neutrons.
The number of Protons should equal the number of Electrons. So It would have (b) electrons.
There are 5 protons in every boron atom and therefore boron-11 isotope has 6 neutrons.
The sum of the protons and neutrons of an atom is equivalent to its relative mass number.
Protons: 5
Neurons: 6
protons and valence electrons
2 protons, 2 electrons, and 1 neutron
a) (well if it has different number of protons or electrons then it would be called an "ionized atom" either positive if more protons or negative if more electrons.) - if there are more neutrons inside the nucleus then protons you got isotopes - b) (well if it has different number of protons or electrons just look at the Periodic Table and count how many protons it has and look at the periodic table that will tell you what an atom will be )
The pair below that describes isotopes of the same element is B, an atom with 6 protons and 6 neutrons-an atom with 6 protons. It is not A, an atom with 6 protons and 8 neutrons- an atom with 8 protons and 6 neutrons. Isotopes of the same element have the same number of protons and electrons, which is the atomic number of the element.
I'm not sure there's a word for it. Ones with fewer neutrons might be "neutron-deficient" (or "neutron poor"), though a) that's probably politically incorrect and b) I think it refers to nuclei that have less than the optimal number of neutrons, even if it isn't actually less than the number of protons.
Boron (symbol B, atom number 5) is build up with:5 protons, 5 electrons and 5 or 6 neutrons, depending on the mass number of the two possible isotopes: B-(10) has 5 neutrons and B-(11) has 6 of them respectively.
An atom with 11 protons, 12 neutrons, and 11 electrons. B. An atom with 11 protons, 10 neutrons, and 11 electrons.An atom with 11 protons, 12 neutrons, and 11 electrons.
protons and valence electrons
(a) a sodium atom with 11 protons, 11 electrons, and 12 neutrons (b) a calcium atom with 20 protons, 18 electrons, and 20 neutrons (c) a helium atom with 2 protons, 2 electrons, and 2 neutrons (d) an iron atom with 26 protons, 26 electrons, and 30 neutrons
2 protons, 2 electrons, and 1 neutron
its atomic numberthe number of neutrons
The Atomic Mass number of an element is the sum of the protons and neutrons in the nucleus of an atom of that element.The relative atomic mass is the average atomic mass number of all the known isotopes of an element.
covalent bond is formed by the sharing of electrons
a) (well if it has different number of protons or electrons then it would be called an "ionized atom" either positive if more protons or negative if more electrons.) - if there are more neutrons inside the nucleus then protons you got isotopes - b) (well if it has different number of protons or electrons just look at the Periodic Table and count how many protons it has and look at the periodic table that will tell you what an atom will be )

Atomic mass is simply the sum of the number of protons and the number of neutrons. If an atom has "A" protons and "B" neutrons, its atomic mass is A + B.
