What causes an atom to have a negative charge?
An atom can be negatively charged if it has an extra electron.An atom can be negatively charged if it has an extra electron.An atom can be negatively charged if it has an extra electron.An atom can be negatively charged if it has an extra electron.
In the normal atom do the electrical charges of the proton balance the electrical charges of the neutron?
Not exactly. Though it IS true that in a normal atom, the number of protons in the nucleus is equal to the number of neutrons, to make the atom electrically neutral (non-ionic), the number of protons (positively charged particles) must equal the number of electrons (negatively charged particles) that surround the nucleus.
What are atomic anions?
An anion is anything with a positive charge. So an atomic anion must be a positively charged atom. Atoms can only gain or lose electrons, which are negatively charged. By losing one or more negative charges, which is to say electrons, an atom becomes positively charged since the protons in its nucleus are no longer balanced by the lost electrons. So overall, an atomic anion is an atom that has given up one or more electrons.
Why did j.j reason the electrons must be a part of the atoms of all elements?
Cathode rays are negatively-charged particles.
What must happen in order for an ion to form?
An ion forms when an atom gains or loses electrons to have a stable electron configuration. When an atom gains electrons, it forms a negatively charged ion (anion), and when it loses electrons, it forms a positively charged ion (cation).

In a negetivly charged ion the number of electrons must be?
In a negatively charged ion formed from a single atom, the number of electrons must be greater than the number of protons in the ion.
What must be true of the number of protons and the number of electrons in an atom if the atom has no charge?
The number of protons must equal the number of electrons in an atom for it to have no charge. Protons are positively charged particles, and electrons are negatively charged particles. A balanced number of protons and electrons results in an atom with a neutral overall charge.
How many protons and electrons are there in oxygen?
Oxygen's atomic number is 8. Thus it has 8 positively charged protons per atom. In order for oxygen to be neutral, it must also have 8 negatively charged electrons in each atom.
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
Why did Thomson think that atom must contain positive charges?
Thomson thought that the atom must contain positive charges because his discovery of electrons inside the atom indicated the presence of negatively charged particles. To balance the negative charge of electrons, there must be positive charges present within the atom.
How did the discovery of electrons show that there are also positively charge parts of an atom?
The discovery of electrons through cathode ray experiments by J.J. Thomson demonstrated the existence of negatively charged particles. It raised the question of what positively charged particles balanced the charge in an atom. Subsequent experiments, like the gold foil experiment by Rutherford, led to the discovery of the atomic nucleus containing positively charged protons, thereby revealing the existence of both negatively and positively charged components within an atom.
How objects become negatively charges?
To become negatively charged, an object must gain electrons from another object
If an atom gives up an electron does it it have a positive charge?
Yes. It becomes a cation (a positive ion). Yes. Each positively charged proton in the nucleus must be cancelled out by a negatively charged electron, or else any noncancelled proton's positive charge will give its atom a positive charge. Likewise the atom that gains the lost electron will have more negatives than positives and will gain a negative charge.
How many electrons does a stable atom of potassium have?
Potassium's atomic number is 19. Thus, it has 19 positively charged protons. To make it neutral, it must also have 19 negatively charged electrons.
In the normal atom do the electrical charges of the proton balance the electrical charges of the neutron?
Not exactly. Though it IS true that in a normal atom, the number of protons in the nucleus is equal to the number of neutrons, to make the atom electrically neutral (non-ionic), the number of protons (positively charged particles) must equal the number of electrons (negatively charged particles) that surround the nucleus.
Who is credited for developing the idea that atoms must have negatively charged electrons?
John Dalton
