How many protons neutrons and electrons are in elements?
The number of protons in an element is its atomic number, which determines its identity. Neutrons can vary for different isotopes of the same element. Electrons equal the number of protons in a neutral atom.
Can you find out the number of electrons by adding protons and neutrons?
To find out the number of electrons in an element you must add the protons and neutrons and subtract that number with the atomic mass, this will determine the amount of electrons because the unknown element could be an isotope and have more than the normal amount of electrons of the non isotope element.
What element on the periodic table has 6 protons 6 neutrons and 6 electrons?
Only carbon has 6 protons. Specifically, this is a neutral atom of the isotope 12C.
The number of electrons in atoms determine in element's propertices?
the valence electrons cause the chemical reations. the valence electrons decide that element attract to which element.
What is the subatomic particle and the calculation derived from it that is not found in the periodic table?
Subatomic particles are protons, neutrons and electrons; the number of protons and electrons (in the neutral state) are equal to the atomic number of an element.
What are found in each element on the periodic table?
Electrons, protons, neutrons
What do you use on the periodic table to determine the number of valence electrons?
To determine the number of valence electrons, you look at the group number of an element on the periodic table.
How can one determine the number of electrons for an element on the periodic table?
To determine the number of electrons for an element on the periodic table, you can look at the element's atomic number. The atomic number represents the number of protons in the nucleus of an atom, which is equal to the number of electrons in a neutral atom.
What information can you gather knowing the atomic number and mass of an element?
If you know the atomic no. and atomic mass, then the no. of electrons, no. of protons and no. of neutrons can also be determined. Atomic No.=No. of electrons = No. of protons. No. of neutrons=Atomic mass-Atomic no. Also, by no. of electrons you can determine its valency and the no. of valence electrons.
How do you determine the mass of an element?
The mass of an element is the sum of the protons and neutrons in an atom. It is usually listed right on the periodic table.
How can you determine the number of valence electrons for an element on the periodic table?
To determine the number of valence electrons for an element on the periodic table, you look at the group number of the element. The group number tells you how many valence electrons the element has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
How do you determine the number of valence electrons for an element on the periodic table?
To determine the number of valence electrons for an element on the periodic table, you look at the group number of the element. The group number tells you how many valence electrons the element has. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on.
How can you determine the number of electrons in an element?
To determine the number of electrons in an element, you can look at the atomic number of the element on the periodic table. The atomic number represents the number of protons in the nucleus of an atom, which is equal to the number of electrons in a neutral atom.
What has 7 valence electrons and 74 neutrons?
An element with 7 valence electrons is likely in Group 17 of the periodic table, such as chlorine. With 74 neutrons, it corresponds to the isotope chlorine-81.
What atomic property is used to make the periodic table?
Firstly an element's mass, then the element's total number of combined protons, neutrons, and electrons.
How many protons neutrons and electrons are in elements?
The number of protons in an element is its atomic number, which determines its identity. Neutrons can vary for different isotopes of the same element. Electrons equal the number of protons in a neutral atom.
