Anion and 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.
Calculate the net charge on a substance consisting of a combination of 7.01013 protons and 4.01013 electrons?
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!)
What is the electric charge on the ion in the compound calcium oxide?
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+
Explain how the atom is neutral as a whole?
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.
How do you know what electron number is in a neutral atom?
Number of electrons = number of protons = atomic number Mass number - number of neutrons = number of protons = number of electrons An ion will either have more or less electrons than protons, thereby making it a charged particle. It is "charged" because there is an abundance of electrons or protons that creates a positive or negative charge. The reason an atom loses or gains electrons to become a charged particle (ion: cation or anion) lies in the octet rule (see related question below). Ions are written with their charge in superscript after the elemental symbol: Li+, Mg+2, Cl-, K+, etc. The number indicates the number of protons or electrons that outnumber the opposite subatomic particle. For example, Mg+2 indicates that there are two more protons than electrons, creating a positive "2" charge. (If no number is given, then it is given that there is "one" more proton or electron). So if we know how many more or less electrons there are than protons, all we need to do is find the number of protons to compare it with. In the example above, there are two less electrons than protons in the magnesium ion. If all magnesium ions contain 12 protons, then there would have to be 10 electrons in the ion. To simplify: Number of protons (or atomic number) - charge of ion = number of electrons
How is an atom given a neg charge?
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.
What is the name given to an atom that gains electrons?
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.
Does AS3- lose or gain electrons?
The ion given is formed when the neutral arsenic atom gains three electrons.

What is name given to the number of electrons an atom gains loses or shares?
Oxidation number
What kind of charge does an object have when it has given away electrons?
negative
write a simple word equation that shows you can figure out the charge of an ion given its numbers of electrons and protons?
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.
What scientist is given credit for measuring the charge on the electrons. He found the charge was large compared to its mass?
This scientist is Robert Millikan (1868-1953).
What will happen when soap bubble is given negative charge or electrons.?
its radius increases due to repulsion of same charges...
Compare the three methods of charging?
There must be electric current for something to be charged. When you are charging something, you will align the electrons towards a given direction. The aprtcle become charged once the electrons are aligned in a given direction.
The number of what identifies whether an atom carries a charge ion or is neutral?
Electrons An atom that becomes stripped of any given number electrons becomes an ion. That is my understanding. :-)
How many extra electrons does an object with a charge of -21mC have?
Charges are quantized. This means that they have quantities. Therefore, q=ne. q is the the charge, n is the number of electrons you are trying to find, and e is the charge on the electron. Remember that your given charge is in micro coulombs, and you'll have to turn that into coulombs. -21x10^-6 c/1.6X10^-19c =n, this will give you the number of extra electrons. hope this helps!
