How many electrons is there in boron if there is a atomic number or 5 and atomic mass of 11?

All you need is the atomic number, which gives the number of protons, in this case, 5. In any neutral atom the number of electrons is the same as the number of protons. So any neutral boron atom will have 5 electrons.

What information does the atomic number of an element give you?
The atomic number is how many protons there are, and since the number of protons is equal to the number of electrons, it is also the number of electrons. You can take the number of protons away from the atomic weight (overall weight) which will give you the number of neutrons. (Electrons don't weigh anything in the atomic weight so you don't need to subtract this as well). Hope this helps :D
What does the atomic number tells you?
The atomic number tells you how many protons and electrons are in a specific element.Atomic number tells us about protons. Number of protons that atom contains.
How many electrons are in the nucleus of an atom with an atomic number of 20?
None. Electrons are found in energy levels outside the nucleus, not in it. An atomic number of 20 tells you there are 20 protons in the nucleus of an atom, and 20 electrons in energy levels (or shells or orbitals depending on which model of the atom you are using) outside the nucleus.
What are two pieces of information that can help you locate an element in the periodic table?
The atomic strucutre and the sub-atomic particle. It place is according to how many shells it has and how many electrons in its outer shell. A new row on the table show a new shell on the element. The atomic number( the bottom) show the number of protons the neuclus has, and the atomic number(top one) shows how many protons and neutrons the atom has together this can be used to see if an isotope is made
What do whole numbers on the periodic table represent?
The whole number, the one at the top, above the element's symbol in the element box, is the atomic number. The atomic number is the number of protons per atom in that particular element. The bottom number, that is always a decimal, is the atomic mass.
How many electrons are on a boron atom?
5- the atomic number of boron is 5. Atomic number is the number of protons and this is the same as the number of electrons in the neutral atom.
How many electrons do boron has?
5 electrons as its atomic number is 5.
How many electrons are in an atom of Boron?
Atomic number = 5So there are 5 electronsAtomic number=protons=electrons
How many protons and electrons in boron if the atomic number is 5?
5 Electrons and 5 Protons
How many electrons does boron have?
Five. The Atomic Number of Boron is 5 so it has five protons and 5 electrons. The Mass number of Boron is 11. Mass minus atomic number = number of neutrons = 6. BORON:Electrons = 5 Protons = 5 Neutrons = 6
How many electrons are in a boron atom?
A neutral boron atom has 5 electrons. On the periodic table, the atomic number of boron is 5. This means that all boron atoms have 5 protons in their nuclei. Protons are positively charged, and electrons are negatively charged, therefore, a neutral boron atom has 5 protons and 5 electrons.
How many valence electrons have boron have?
3 valence electrons. As the atomic number of boron is 5, it would have 2 electrons in the first shell and 3 valence electrons in the second shell.
How many protons electrons and nuetrons does boron - 10 have?
Boron's atomic number is 5. So there are 5 protons and 5 electrons. In Boron-10, there are 5 neutrons (10 - 5 = 5)
How many valance electrons do boron have?
Boron's atomic number is 5. Thus, its electron configuration is 1s2 2s2 2p1. If you add up the number of electrons in the "2" shell, which is boron's valence shell, you get 2 + 1 = 3 valence electrons.
How many valence electrons does have boron have?
3
How many electrons does an boron have?
Boron's atomic number is 5. Thus, it has 5 protons per atom. To be electrically neutral then, it must also have 5 electrons per atom.
How many electrons protons neutrons boron have?
5 Protons,6 Electrons,5 Neutrons
