What are atoms of the same element with different numbers of electrons?
Usually, an atom has the same number of protons as electrons, but when the number of electrons is changed, the atom is considered ionic. An atom that has lost an electron is called an anion, and an atom that has gained an electron is called a cation. One example of a cation is a potassium ion, or K+, and one example of an anion is chloride,(a chlorine ion) or Cl-
What is the symbol for a cation and anion that are isoelectronic with krypton?
Atoms are isoelectronic when they have the same electron configuration. Therefore, an anion isoelectronic to krypton is bromide. A cation isoelectronic to krypton is rubidium.
What do you get when the number of electrons is not the same as the number of protons?
Any imbalance in proton/electron number in an atom results in a charge. Fewer electrons makes a positive charge, while more electrons make a negative charged (obviously). Charged atoms are known as ions.
How does a cation differ from an anion?
A cation is a positively charged ion formed by losing electrons, while an anion is a negatively charged ion formed by gaining electrons. Cations are attracted to cathodes, while anions are attracted to anodes in electrolysis.
What elements have the same number of valence electrons as carbon?
It is silicon that has the same number of valence electrons as carbon. Silicon sits right below carbon on the periodic table.
Can a cation and anion be isoelectronic from the same period?
Yes, a cation and an anion can be isoelectronic if they have the same number of electrons. For example, in the third period of the periodic table, a sodium cation (Na+) and a fluorine anion (F-) are isoelectronic because they both have 10 electrons.

What is the difference between a nonmetal atom and an anion of the same element?
the number of electrons in the outer shell .. for metals its less than 4 .. for non metals its more than 4 .. for semi its 4
How does the atomic number of an element compare with the number of electrons that normally surround the nucleus?
If the atom is atomically neutral (meaning that it does not hold a charge and it's not a cation or an anion), then the number of electrons and protons in an atom will be the same. If they do hold a charge (say if it is an anion), then it would have an extra electron. If it was positively charged, then an electron would be lost.
What is the symbol for a cation and anion that are isoelectronic with krypton?
Atoms are isoelectronic when they have the same electron configuration. Therefore, an anion isoelectronic to krypton is bromide. A cation isoelectronic to krypton is rubidium.

What type of electrons will a negatively charged atom have?
All electrons are the same. A negatively charged atom would be an anion.
Is the Atomic weight for an element the same when it is in an anion or cation?
The weights of atoms are based primarily on the number of protons and neutrons in an atom. This is because protons and neutrons are many times the weight of electrons. Since electrons contribute a minuscule amount, even on the atomic level, to the mass of the atom, the mass of the atom is taken to be the same whether it is a anion of a cation. Remember, it is the number of electrons in an atom that determines whether it is an anion, cation, or a neutral atom. If there is a different number of neutrons it is called an isotope, and will have a different mass. If it has a different number of protons, it is a different atom and will have a different mass.
Where are elements with the same number of valence electrons?
Elements with the same number of valence electrons are found in the same group or column of the periodic table. This is because elements in the same group have the same number of valence electrons, which determines their chemical properties. For example, all elements in group 1 have 1 valence electron.
Which elements have the same number of valence electrons as beryllium?
For example calcium and magnesium.
How does a cation differ from an anion?
A cation is a positively charged ion formed by losing electrons, while an anion is a negatively charged ion formed by gaining electrons. Cations are attracted to cathodes, while anions are attracted to anodes in electrolysis.
