It contains 10 protons and 10 electrons (no. of protons =no. of electrons in ground state)
Number of neutrons=Mass number of element- number of protons
=19-10
=9

How many protrons and neutrons does boron contain?
5 Protons, 6 Neutrons. For future reference, the protons is the atomic number (right above the element symbol) To get the neutrons you subtract the atomic mass (underneath the symbol) by the number of protons. You have to round this number.
What is the number above the elements symbol?
the number above the symbol is the atomic....... of that element.
What element has 28 protons 30 neutrons and 28 electrons?
Nickel (Ni) is a chemical element with the chemical symbol Ni and atomic number 28. Nickel has: protons=28 neutrons=30 electrons=28 atomic mass=58 atomic #=28
Is Krypton an element compound or mixture?
Krypton is an element with symbol Kr and atomic number 36.
How man protons electrons and neutrons are in sulfur?
Sulfur is a chemical element with the symbol S and atomic number 16. It has 16 protons, 16 neutrons and 16 electrons.
How do you figure neutrons on periodic chart?
by subtracting the atomic number from the mass number. the atomic number is the one under the element's symbol and the mass number is the one above the element's symbol.
What does atomic mass number elements symbol elements name and atomic mass tell you about the element?
The element symbol represents one mole of element , atomic number represents number of protons, atomic mass represents sum of protons and neutrons.

What is the atomic mass and symbol of an element with 34protons 33 neutrons 34 electrons?
The 34 protons means that this is the element that has an atomic number of 34, which is selenium. The mass number for the isotope given is 67, which is the sum of the protons and neutrons. Mass number is not the same as atomic mass. Atomic mass is the total mass of the protons, neutrons, and electrons in an atom.
Which element have 13 neutrons?
The element with 13 neutrons is aluminum (symbol Al) which has an atomic number of 13.
The symbol for the chemical element hydrogen is H and its atomic number is 1 what is the symbol and atomic number for the element sodium?
The symbol for the chemical element sodium is Na and its atomic number is 11.
What is the number above the elements symbol?
the number above the symbol is the atomic....... of that element.
What info can be found in a square on the periodic table?
You can find the Atomic Number, Atomic Mass, The Element symbol and Name and sometimes, the numbers of the electrons in each shell. (for a Bohr model)Also element symbol can be called atomic symbol.The information is the atomic number, also stands for how many electrons and protons there are in that element, also it tells what the atomic abbreviation is and the real name.Each square on the periodic table gives information about an element. On many printed periodic tables we can have atomic number, atomic weight and some other properties like melting and boiling points may also be included.the atomic number and the atomic mass. the atomic number tells you how many neutrons and electrons are in the atom, and the atomic mass tells you the combined amount of protons and neutrons and that element. there is also the symbol of the element, which is the symbol for it's name, and most tables provide the name of the elements.Most basic periodic tables contain four pieces of information for each element: the element's name, symbol, atomic number, and atomic mass. For example, the first element would have an "H", the name Hydrogen, a number 1, and a number 1.0079. H is hydrogen's symbol. The 1 is hydrogen's atomic number, which is the number of protons its nucleus. The 1.0079 is hydrogen's atomic mass.More detailed periodic tables may include number of valence electrons, electron configuration, electronegativity, ionization energy, and other properties.It varies depending on which table you use. A general table will give you the atomic number, element symbol, and atomic mass.The periodic table contains several pieces of information about each element. The element's square on the table includes its atomic symbol, atomic number, and atomic weight.Each square represents the name of the element, the atomic number, and the atomic mass of the element.
What does the symbol inside an elements square mean?
The symbol of an element is an abbreviation for the element's name, and it is derived either from the English or the Latin name. For example: Bromine's symbol is Br. The symbol inside an element's square is the element's atomic number, or the number of protons and neutrons in the element.
What element has 28 protons 30 neutrons and 28 electrons?
Nickel (Ni) is a chemical element with the chemical symbol Ni and atomic number 28. Nickel has: protons=28 neutrons=30 electrons=28 atomic mass=58 atomic #=28
