An ion exists as an atom or a molecule where the total number of protons in the nuclei do not equal the atom/molecule's electrons. An example is Ca2+. It has 2 less electrons than it has protons.
No, nitrogen is not negatively charged. It is a neutral element with a charge of 0, meaning it has an equal number of protons and electrons.
Water is a neutral molecule, meaning it does not have a positive or negative charge overall.
A positively or negatively charged object can have multiples of the fundamental charge because the charge on an object is quantized, meaning it can only exist in discrete amounts. The fundamental charge is the smallest unit of charge found in nature, and objects can accumulate multiple units of this charge through gaining or losing electrons.
Negatively charge
False, electrons are negatively charged whereas neutrons have no charge. An electron is of opposite charge to a proton which has a positive charge.
No. Any element on its own is neutral, meaning it does not have a charge. Carbon rarely forms ions, and when it does they are negatively charged.
Rubber is a neutral substance, meaning it has no overall charge. However, it can become charged through processes like friction, where it can become negatively charged due to the transfer of electrons.
H2O (water) is a neutral molecule, meaning it has no overall charge. It is composed of two positively charged hydrogen atoms and one negatively charged oxygen atom, resulting in a balanced distribution of charge.
Electrons are negatively charged.
electron
Negatively charged
They are ALWAYS negatively charged. If positively charged it would be a positron and not an electron.
