The chemical element with 20 protons and 20 neutrons is Calcium(Ca). The number of protons is equal to the number of electrons, and the number of electrons is equal to the atomic number.
An ION NB When an atom has a balanced(equal) number of protons and electrons it is named an ATOM If an atom has an imbalance(unequal) number of protons and electrons it is named an ION (NOT an atom). e.g. Sodium (Na)_ An atom of sodium has 11 protons (+) and 11 electrons(-). When this atom is ionized it loses ONE electron. So the count is now 11 protons(+) and 10 electrons(-). It is now an ION (NOT an atom) and is symbolically represented by ' Na^(+)'. The positive(+) because 11 protons (11+) and electrons(-) because 10 electrons (10-) Adding we have 11+ 10- = 1+ Hence the plus (+) as the ionic charge, represented by ' Na^(+) '. Conversely Chlorine(Cl) An atom of chlorine has 17 protons (+) and 17 electrons(-). When this atom undergoes electron affinity it gains ONE electron. So the count is now 17 protons(+) and 18 electrons(-). It is now an ION (NOT an atom) and is symbolically represented by ' Cl^(-)'. The positive(+) because 17 protons (17+) and electrons(-) because 18 electrons (18-) Adding we have 17+ 18- = 1- Hence the negative (-) as the ionic charge, represented by ' Cl^(-) '.
(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
There are less electrons than protons in a positive ion. More information is needed to determine the exact number. Here is an example: How many electrons are in a carbon ion with a positive charge of positive 2e? There are 6 protons in carbon (since it is element number 6). Since it has a charge of +2, there will be 2 less electrons than protons, so the number of electrons would be 4.
No, sodium is not a subatomic particle. Sodium is a chemical element with the symbol Na and atomic number 11. Subatomic particles are particles smaller than an atom, such as protons, neutrons, and electrons.
The resulting nucleus has 6 protons. Boron-10 has 5 protons, and absorbing a neutron increases the atomic number by 1 to become carbon-11, which has 6 protons. The emission of an alpha particle (helium nucleus with 2 protons) leaves behind a nucleus with 6 protons.
For an neutral element that has the same number of electrons and protons, the element with 11 electrons is Na, sodium.
11 protons and 10 electrons
none because the number of protons and electrons have to be the same.
Yes, sodium have protons. There are 11 protons and 10 electrons
- The atomic symbol is only an abridged form of the name of a chemical element. - The chemical symbol of neon is Ne; the atomic number is 10. - The atomic number is equal to the number of protons and electrons. - Number of neutrons = Atomic mass of an isotope - Atomic number
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.
The atomic number of sodium is 11 which means it has 11 protons and 11 electrons.
The ion Na+ has 11 protons, 12 neutrons, and 10 electrons. This is because sodium has an atomic number of 11, meaning it naturally has 11 protons and 11 electrons, but as an ion with a +1 charge, it has lost 1 electron.
sodium has more protons and neutrons. electrons have practically no mass, valence electrons are just outer orbital electrons. sodium has 11 protons, 11 electrons, and 12 neutrons. Mass is 23. neon has 10 protons, 10 electrons, and 10 neutrons. Mass is just 20. The neon atom has 10 protons and 10 neutrons for a mass number of 20. The sodium atom has 11 protons and 12 neutrons for a mass number of 23. The number of valence electrons has no bearing on mass number or atomic weight.
A sodium ion with 11 protons and 10 electrons has a net charge of +1 because the number of protons (positive charge) is greater than the number of electrons (negative charge) by 1.
Neon has 10 protons and 10 electrons per atom. 20Ne is its most common isotope. It has 20 - 10 = 10 neutrons.
The cation of sodium has 11 protons and 10 electrons.
