20 protons, 18 electron's, and 20 neutrons
1) it's spelt Calcium and 2) 20 protons, 20 electrons, 20 neutrons
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
The three main subatomic particles that form an atom are protons, neutrons, and electrons. The center of the atom is called the nucleus.The protons have a positive charge, the neutrons have no charge, and the electrons have a negative charge.
Ca (2+) I think because since there are two less electrons then the charge would become positive.
Carbon-12 has 6 protons, neutrons, and electrons.
20 protons and 18 electrons
Protons have a positive charge, electrons have a negative charge, and neutrons are neutral and have no charge.
Calcium has 20 protons and electrons and a variable number of neutrons, depending on the isotope.
20 p+ 20 n
Protons and electrons both have a positive or negative charge, but neutrons have no charge.
protons are positive
Electrons have no relevant mass, and protons and neutrons both have the mass of 1u. If Calcium has the number 20, it has 20 protons (and electrons). It's mass is about 40u. Core Mass - Protons = Neutrons 40u - 20u = 20u, this means Calcium has 20 electrons, 20 protons and 20 neutrons.
No. Protons are positive and neutrons are neutral. Electrons are negative.
Protons- positive neutrons- none electrons-negative
Electrons: Negative Protons: Positive Neutrons: Neutral
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.
Um, the element calcium? Protons, neutrons, electrons..
