Is a calcium atom larger than a barrium atom?
Calcium contains 20 protons, 20 neutrons and 20 electrons (on average). Barium has 56 protons 81 neutrons and 56 electrons (again, on average). So, Barium is much larger.
Three basic parts of an atom?
An atom contain protons, neutrons and electrons.
Which element has 20 protons 20 neutrons and 20 electrons?
Calcium has 20 protons and electrons. The symbol for calcium is Ca and its atomic number is 20.
What are three types of subatomic particles?
In the atom are: neutrons, protons, electrons.
Is boron protons electrons or neutrons?
Boron is an atom or element, and it contains protons, electrons, and neutrons.
How many protons and electrons does a calcium atom have?
Calcium has 20 protons, 20 electrons and 20 neutrons in its most commonly found isotope.
What are the elements that formed the calcium?
Calcium is an element, which means that it is made up protons/electrons and neutrons. Each calcium atom contains a total of 20 protons/electrons, and 20 neutrons.
Which of the has an electric charge?
(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

What are the subatomic particles of calcium?
Calcium has 20 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a calcium atom = Mass number - 20
An atom has 11 protons 13 neutrons and 11 electrons What are possible isotopes of this atom?
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.
What is the element that has 20 neutrons?
Several can. Perhaps you meant to ask which has 20 protons, in which case the answer is calcium. (Calcium is also one of the elements that can have 20 neutrons, but it's not the only one.)
Which element has 20 protons 20 neutrons and 20 electrons?
Calcium has 20 protons and electrons. The symbol for calcium is Ca and its atomic number is 20.
What three major parts of a atom?
The three constituents that make an atom are protons, neutrons, and electrons.
