What else can I help you with?
Do cations lose electrons?
Yes, cations are formed when an atom loses one or more electrons, resulting in a positively charged ion. This loss of electrons creates an imbalance between the number of protons and electrons in the atom, leading to a net positive charge.
When does a piece of matter have a positive charge?
First of all, acknowledge that the charge of one proton (which cannot move) = the charge of an electron (can move). The electrons on that particular atom or object lets say, transfer from itself with the help of extra energy (e.g. friction or mere contact) so then the atom which was once neutral (same number of protons to electrons) and there are more protons than electrons because the electrons just left the atom. This means that there are more positive charges than negative ones, which means there is an overall positive charge, giving a positive electric charge.
What causes the across period trends?
Across-period trends in the periodic table, such as changes in electronegativity, atomic radius, and ionization energy, are primarily influenced by the increasing nuclear charge as you move from left to right. This greater positive charge attracts electrons more strongly, leading to a decrease in atomic radius and an increase in ionization energy. Additionally, the effective nuclear charge experienced by outer electrons increases, enhancing their ability to attract additional electrons, which explains the rising electronegativity. These trends reflect the underlying electronic structure and the interactions between protons and electrons in the atom.
Does all the electrons in an atom have similar amounts of energy?
If it exists at any temperature above absolute zero, -273C, it must have at least kinetic energy. Near any other charge, which it will be in any realistic consideration, it will also have potential energy.
What kind of charged particles does an atom contain?
An atom contains charged particles called protons, which have a positive charge, and electrons, which have a negative charge. Protons are located in the nucleus of the atom, while electrons orbit around the nucleus in specific energy levels.

What are elements lose electrons and form positive ions named?
The elements that lose electrons and form positive ions are called metals. They will lose the electrons from their highest levels of energy to gain a more positive charge and form positive ions.
An atom with more electrons would have charge?
An atom with more protons than electrons will have a positive charge. Neutral atoms can loose electrons if they are subjected to some kind of energy. Sometimed illumination with the correct color of light is sufficient to knock electrons off atoms.
What can happen to an electron in an atom when it gains or loses energy?
it gains or acquires a charge either positive or negative so when it gains energy, it aquires a negative charge then when it loses energy, it aquires a positive charge

Is positive charge spread equally over an atom?
No, positive charge is concentrated in the nucleus of an atom, which contains protons. Electrons, carrying negative charge, are located in energy levels surrounding the nucleus. The positive charge of the protons is concentrated at the center of the atom.
Is the number of valence electrons in an atom equal to its Zeff value?
No, the number of valence electrons in an atom is not equal to its effective nuclear charge (Zeff) value. Valence electrons are the electrons in the outermost energy level of an atom, while the Zeff value represents the net positive charge experienced by an electron in the outermost energy level.
Why is matter neutral?
Matter is neutral because it contains equal numbers of positive protons and negative electrons. Protons carry a positive charge, while electrons carry a negative charge. These charges balance each other out, resulting in an overall neutral charge for matter.
What energy level shell would have the greatest potential energy?
The energy level shell farthest from the nucleus would have the greatest potential energy. As electrons move farther from the nucleus, their potential energy increases due to the increasing distance from the positive charge of the nucleus. This is in line with the understanding that potential energy decreases as an object gets closer to a source of attraction.

Is the effective nuclear charge equivalent to the number of valence electrons in an atom?
No, the effective nuclear charge is not equivalent to the number of valence electrons in an atom. The effective nuclear charge is the net positive charge experienced by an electron in a multi-electron atom, taking into account the shielding effect of inner electrons. Valence electrons are the electrons in the outermost energy level of an atom that are involved in bonding.
Do solar energy panels have positive and negative charges?
Solar panels generate electricity through photons from the sun knocking electrons loose from atoms in the panel material. This creates a flow of electrons, which creates a positive charge on one side of the panel and a negative charge on the other.
