24 electrons, remember the atomic number of an element tells you how many protons it has. The number of protons = the number of electrons (if the atom isnt charged)

What is the charge of Cr in Cr2O72?
Since oxygen atoms can only accept two electrons, the balance of charges for the overall neutral molecule suggests that the two chromium atoms must each have donated half of the electrons to the oxygen atoms. Therefore, the total number of electrons required for all three oxygen atoms to reach a noble gas configuration is 3 atoms*2 electrons/atom=6 electrons Dividing this up between the two chromium atoms: 6 electrons/2 atoms=3 electrons/atom Therefore, each chromium atom bears a positive charge (since it donated electrons) of 3+.
How many neutrons and protons does Chromium 3 have?
Chromium's, or Cr's, atomic number is 24. Therefore each chromium atom has 24 protons. 52Cr is the most stable isotope of chromium and has 52 - 24 = 28 neutrons. The chromium ion, Cr3+, means it has 3 less electrons than neutral chromium, and thus the number of protons and neutrons are unaffected.
What is true about a atom that has a neutral charge?
The number of protons is equal to the number of electrons.
If a neutral atom of 22 protons how many electrons does an atom contain?
22. The electrons have a charge of -1, and protons have a charge of +1. In order for the charges to cancel out and make the atom neutral, there must be an equal number of each.
Why does an atom that has the same number of protons as electrons is electrically neutral?
Protons are positively charged while electrons are negatively charged. So an atom with equal numbers of both protons and electrons cancel each other's charges making the atom electrically neutral.
What is the number of electrons for the element antimony in a neutral atom?
Each neutral atom of antimony contains 51 electrons, the same as the atomic number of antimony.
How does the number of electrons cmpare with the number of protons in a neutral atom?
In a neutral atom, the number of protons and the number of electrons is the same. Protons have a positive charge and electrons have a negative charge. If the numbers of each are equal, then the charges cancel out to zero and the atom is neutral.

How may electrons does each atom of carbon have?
A neutral carbon atom has 6 electrons in the following configuration: 1s2 2s2 2p2
How can an atom be electrically neutral charged when it contain particles that are charged?
an atom is electrically neutral if the protons and electrons are the same number. ex: if you have 16 protons and 16 electrons its is neutral
Why are protons related to electrons with a negative charge?
In a neutral atom, the number of protons is equal to the number of electrons. Since each proton has a charge of +1, and electrons have a charge of -1, the positive and negative charges balance each other, and the atom will be neutral.
What is true about a atom that has a neutral charge?
The number of protons is equal to the number of electrons.
If a neutral atom of 22 protons how many electrons does an atom contain?
22. The electrons have a charge of -1, and protons have a charge of +1. In order for the charges to cancel out and make the atom neutral, there must be an equal number of each.
How many electons are in a neutral atom?
A neutral atom has as many electrons as protons. This is because protons have a positive charge and electrons have a negative charge, but because there are the same number of them, they cancel each other out.
What scientific element has 20 electrons?
Calcium has twenty electrons in each atom.
Why does an atom that has the same number of protons as electrons is electrically neutral?
Protons are positively charged while electrons are negatively charged. So an atom with equal numbers of both protons and electrons cancel each other's charges making the atom electrically neutral.
