Is a molecule of dissimilar elements with a net charge remaining is called a polyatomic ion?
No, a polyatomic ion is a molecule composed of two or more atoms covalently bonded that carries a net charge. A molecule of dissimilar elements with a net charge is generally referred to as an ion, but not specifically as a polyatomic ion unless it contains multiple atoms of different elements.
What is Br2 atom ion or molecule?
No, they are covalent bonds. An ionic bond is formed between a group 1 metal and Br.
Does an ion refer to two or more atoms held together by covalent bonds?
No. What you describe is called a molecule. An ion is an atom or group of atoms with a net electrical charge.
What is the difference between a positively charged molecular ion and positively charged group of atoms?
Ions can be created by both chemical and physical means. In chemical terms, if a neutral atom loses one or more electrons, it has a net positive charge and is known as a cation. If an atom gains electrons, it has a net negative charge and is known as an anion. An ion consisting of a single atom is an atomic or monatomic ion; if it consists of two or more atoms, it is a molecular or polyatomic ion.
How is a negative ion is formed?
It gains one or more electrons.

What is a positive and negative ion?
when an atom loose electron it become negative ion and when it gains electron it become positive ion
What is the relationship between the net force acting on an object and the direction in which the object moves?
The net force acting on an object determines the acceleration of the object in the direction of the force. If the net force is in the same direction as the object's motion, the object will accelerate in that direction. If the net force is in the opposite direction, the object will decelerate or change direction.
Does an ion atom or molecule have an electric charge?
Yes, an ion is an atom or molecule that has an electric charge. This charge is due to the loss or gain of electrons, resulting in a net positive or negative charge.
What is Br2 atom ion or molecule?
No, they are covalent bonds. An ionic bond is formed between a group 1 metal and Br.
Does an ion refer to two or more atoms held together by covalent bonds?
No. What you describe is called a molecule. An ion is an atom or group of atoms with a net electrical charge.
What are the differences between molecule and molecular ion?
A molecular ion is a type of ion that either has less or more electrons than it has protons. A polar molecule is a molecule that has positive charges near its center and negative charges outside that center.
What has a positive ion?
A positive ion is an atom or molecule that has lost one or more electrons, resulting in a net positive electrical charge. Examples include the hydrogen ion (H+) and the sodium ion (Na+).
A is a tightly-bound group of atoms that behaves as a unit and carries a net charge?
It is a polyatomic, literally meaning many like atoms.
What is the general term for an ion such as phosphate which is a molecule that has an overall electric charge?
The general term for an ion with an overall electric charge is "polyatomic ion." These ions are composed of multiple atoms covalently bonded together but possess a net electric charge.
What is the difference between a positively charged molecular ion and positively charged group of atoms?
Ions can be created by both chemical and physical means. In chemical terms, if a neutral atom loses one or more electrons, it has a net positive charge and is known as a cation. If an atom gains electrons, it has a net negative charge and is known as an anion. An ion consisting of a single atom is an atomic or monatomic ion; if it consists of two or more atoms, it is a molecular or polyatomic ion.
What determines which direction facilitated diffusion occurs?
The concentration determines the directions based on the net flux. The net flux moves from a higher concentration to a lower concentration.
