When the cation in a compound is replaced does it stay charged?
When the cation in a compound is replaced, the charge on the cation can change depending on the properties of the new cation. Some cations have fixed charges, while others can have variable charges. Therefore, the charge on the cation may or may not stay the same when it is replaced in a compound.
How atomic number better than atomic mass?
No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
What would you need to tell the number of protons and electrons present in an ion?
The atomic number of the element in the ion, when there is only one such element, and the atomic charge on the ion. For example, in Na+1, the atomic number is 11; this gives the number of protons. The number of electrons is equal to the atomic number minus the charge on the ion, in this instance, 10 electrons. If the sign on the ion is negative, as in O-2, remember that subtracting a negative number is equivalent to adding the positive number of the same magnitude. Thus, oxygen has an atomic number of 8, and 8 - (-2) equals 10 electrons.
Is an ion an or molecule that carries a charge?
An ion is a particle that carries a charge, either positive or negative, due to losing or gaining electrons. It can be a single atom or a group of atoms that have an overall charge. A molecule is a group of atoms held together by chemical bonds and may or may not carry a charge.
What is the relationship between a atomic number and an atomic mass number?
Atomic number: number of protons in a nucleus unique to an element Atomic mass number: number of protons + number of neutrons in a nucleus. May be a small range of values for a given element. Very roughly the atomic mass number is double the atomic number. For large elements it is more than double.

What do protons and neutrons equal?
Protons and neutrons together make up the atomic nucleus. Protons are positively charged particles, while neutrons have no charge. The number of protons in an atom determines its atomic number, while the total number of protons and neutrons together determine its atomic mass.

How may electrons can chlorine donate and receive?
Chlorine can donate one electron to form an anion with a -1 charge or receive one electron to form a cation with a +1 charge.
In a crystal of an ionic compound each cation is surrounded by the number of?
In a crystal of an ionic compound, each cation is typically surrounded by multiple anions. The number of surrounding anions depends on the coordination number of the cation, which is the number of nearest neighbor ions directly surrounding the cation in the crystal lattice.
How may neutrons does neon have?
Number of neutrons = Atomic mass - Atomic number Atomic number of neon: 10 Atomic mass: depending on the neon isotope, each isotope has a different mass
Is the number of neutrons equal to the atomic number?
In an atom, the number of protons is always similar to its atomic number. (The number of nutrons may be similar or different.)
What is the relationship between the atomic number and the atomic mass number?
Atomic number: number of protons in a nucleus unique to an element Atomic Mass number: number of protons + number of neutrons in a nucleus. May be a small range of values for a given element. Very roughly the atomic mass number is double the atomic number. For large elements it is more than double.
What particle has a zero electric charge?
1. photon has zero charge.there may also be sub atomic particle with zero charge.
Is an ion an or molecule that carries a charge?
An ion is a particle that carries a charge, either positive or negative, due to losing or gaining electrons. It can be a single atom or a group of atoms that have an overall charge. A molecule is a group of atoms held together by chemical bonds and may or may not carry a charge.
The number of neutrons is equal to the atomic number true or false?
False as a generalization but true for some isotopes. The atomic number is the number of protons in a nucleus, which may coincidentally be the same as the number of neutrons but is not required to be.
