Normally, atoms have the same number of protons and electrons. Protons are positively charged, electrons are negatively charged. To become positively charged, an atom must lose an electron (Thus there'll be more protons than electrons). Such atoms are called cations (positively-charged ions).
What else can I help you with?
Is the size of a positive ion generally bigger or smaller than the size of the neutral form which it forms?
A positive ion is generally smaller in size than the neutral form from which it forms. This is because when an atom loses an electron to become a positive ion, the remaining electrons experience a stronger attraction to the nucleus, leading to a more compact arrangement.
What must happen to form a positive or negative ion?
if a substance loses one or more electrons it becomes positively charged and when it gains an electron it becomes negatively charged
What do we call an atom that has an overall positive charge?
An atom with an overall positive charge is called a cation. Cations are formed when an atom loses electrons, leaving it with fewer electrons than protons, resulting in a net positive charge.
What is an atom with an electrical charge on it called?
An atom with a charge (either positive or negative) is called an "ion." An ion with a positive charge is called a "cation" and an ion with a negative charge is called an "anion ."
How does a positive ion become a neutral atom?
A positive ion can become a neutral atom by gaining electrons. When a positive ion gains one or more electrons, it becomes neutral because the negative charge of the electron(s) cancels out the positive charge of the ion.
When is a positive ion form?
A positive ion is formed when an atom loses one or more then electrons.
Is the size of a positive ion generally bigger or smaller than the size of the neutral form which it forms?
A positive ion is generally smaller in size than the neutral form from which it forms. This is because when an atom loses an electron to become a positive ion, the remaining electrons experience a stronger attraction to the nucleus, leading to a more compact arrangement.
Which atom requires the least amount of energy to form a positive ion '?
K
What is the ion charge of a helium atom Is it plus 1?
Helium atom is neutral and has no charge. It becomes a positive ion with a charge of +1 when it loses an electron.
Is an ion atom with a charge?
An ion is an atom with a positive or negative charge.
When an atom loses one or more electrons to form a positive ion the energy is?
When an atom loses one or more electrons to form a positive ion, the energy required is known as ionization energy. This is the energy needed to remove an electron from the atom.
An atom is called an ion if there?
An atom is called an ion if there is a charge on it - positive or negative.
What is the difference of an atom or an ion?
A ion is an electrically charged atom, positive or negative.
What do you call an atom when it has an electric charge?
An atom with an electrical charge is called an ion.
What atom can form a negative ion but usually forms a positive one?
Non Metals
What is going to happen to the size of a positive ion as compared to the original atom?
The positive ion has donated an electron to another atom making the other atom a negative ion and much larger in radius. The positive ion is now much smaller in radius.
What happens when an atom loses an electron form its outermost shell?
It becomes a positive ion, and also connects with the atom that stoles its electron.
