cations are positively charged ions that are produced when an atom loses electrons and anions are negatively charged ions that are produced when an atom gains electrons. we know that a atom needs 8 electrons in valance shell to or octet configuration ; duplet (2 electrons in outer most shell) , if an atom have atomic number 11 that is sodium and it can be written has 2,8,1 and it losses 1 electron to get duplet confg. as electrons are decreased they become positive ion or cations . anions are formed when number of electrons are increased by gaining electron to get given confg. ex: oxygen , atomic number 8 and written as 2,6 and it gains 2 electrons for octect confg.
Because protons and electrons have the same magnitude of electric charge each, but of opposite signs, this charge would be 7.01013 - 4.01013 = 4. (Only one significant digit is given, and the question itself is suspicious, because fractional protons and electrons do not exist!)
Atoms are made of protons, neutrons and electrons. Protons are positively charged, electrons negatively charged and neutrons have no charge. Since the number of protons is equal to the number of electrons in any given atom, the overall charge of the atom is neutral (negative charge of one electron cancels the positive charge of one proton) Atoms that are positively charged (cations) have lost one or more electron(s). Atoms that are negatively charged (anions) have gained one or more electrons.
Well the charge on the compound would be stable (0) when bonded, because the Calcium has given it's electrons to the Oxygen atom. But the charge on the calcium ion itself would be 2+
Yes, current is the flow of electric charge, typically carried by electrons in a conductor. It is measured in amperes and represents the rate at which electrons pass through a given point in a circuit.
The ion given is formed when the neutral arsenic atom gains three electrons.
In simple terms, an atom is made up of Protons, Neutrons, and Electrons. Protons have positive charge (+1), Neutrons have no charge (0), and Electrons have negative charge (-1). If an atom gains or loses Electrons, it's net charge changes. To result in a negative charge, the atom must have more Electrons than Protons.
It is an ION Answer: Yes it is an Ion, but no, it is formally called an Anion. Because it gained an electron it has become negatively charged. If it loses an electron it becomes a cation.

cations are positively charged ions that are produced when an atom loses electrons and anions are negatively charged ions that are produced when an atom gains electrons. we know that a atom needs 8 electrons in valance shell to or octet configuration ; duplet (2 electrons in outer most shell) , if an atom have atomic number 11 that is sodium and it can be written has 2,8,1 and it losses 1 electron to get duplet confg. as electrons are decreased they become positive ion or cations . anions are formed when number of electrons are increased by gaining electron to get given confg. ex: oxygen , atomic number 8 and written as 2,6 and it gains 2 electrons for octect confg.
The process by which an atom is given a net charge by adding or removing electrons is called ionization. When an atom gains an electron, it becomes negatively charged (anion), and when it loses an electron, it becomes positively charged (cation).
The given electron configuration corresponds to the ion with a charge of -2, which is the oxide ion (O^2-). This ion is formed by the element oxygen when it gains two electrons to achieve a stable electronic configuration.
If there are more electrons than protons, then the ion charge is negative. If there are more protons than elections, then the ion charge is positive.
Atoms that have lost or gained one or more electrons are called ions.An atom that has gained and electron is an anion; and atom that has lost an electron is a cation. Gaining an electron means the anion has a negative charge; losing one or more electrons means the atom has a positive charge.
Electrons An atom that becomes stripped of any given number electrons becomes an ion. That is my understanding. :-)
