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.
What is the total charge on a neutral atom?
By definition, atoms have no overall electrical charge. That means that there must be a balance between the positively charged protons and the negatively charged electrons. Atoms must have equal numbers of protons and electrons. In our example, an atom of krypton must contain 36 electrons since it contains 36 protons.
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.

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.
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 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.
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.
An atom can form a positive ion by?
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).
Are all atoms neutral?
Can atoms become neutral and howAtoms are already neutral because they have both protons which are positive charged and electrons which are negatively charged. it has to be nueral because of the the same number of both negative and positive particles.
How objects become negatively charges?
To become negatively charged, an object must gain electrons from another object

What was Ernest Rutherford's biggest contribution to chemistry?
In 1911, Rutherford proposed a new model for the atom. His experiments were the first to show that the atom must consist of a very tiny positively charged nucleus surrounded by negatively charged electrons. (For the record, Rutherford also discovered and named alpha, beta and gamma radiation.)
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
