How do you know if an atom is positive or negative?
If the atom has more electrons than protons, it is a negative ion, or ANION. If it has more protons than electrons,it is a positive ion.
What is the charge of an ion that contains 24 protons and 21 electrons?
Cr3+
Cr3+ represents an ion with 24 protons and 21 electrons.
How many electrons are in the ion ni2 +?
Nickel Ni28 has 28 electrons. 18 electrons fill up the third electron shell leaving 10 valance electrons. 2 electrons in the 4s and 8 elections in the 3d. When Nickel becomes Ni+2 Nickel has lost 2 electrons leaving the atom with only 8 valance electrons.
Are neutrons positive or negative?
Miller, a UW physics professor, has found that the neutron has a negative charge both in its inner core and its outer edge, with a positive charge sandwiched in between to make the particle electrically neutral.
Are electrons positive or negative?
negative charge
Protons and Electrons A proton carries a positive charge (+) and an electron carries a negative charge (-), so the atoms of elements are neutral, all the positive charges canceling out all the negative charges. Atoms differ from one another in the number of protons, neutrons and electrons they contain.
What ion has 22 protons 26 neutrons and 19 electrons?
By referring to a periodic table or list of elements, we see that the element with atomic number 22 is titanium (Ti). The mass number of this isotope of titanium is 22 + 26 = 48 (the sum of the protons and neutrons).
What is the charge of chromium 24?
Chromium was discovered (1797) by the French chemist Nicolas-Louis Vauquelin and isolated as the metal a year later; it was named for its multicoloured compounds….Read a brief summary of this topic.
| atomic number | 24 |

What is a positive atom?
The atom that has lost an electron becomes a positively charged ion (called a cation), while the atom that picks up the extra electron becomes a negatively charged ion (called an anion).
What is the name of Ni2+?
Nickel (II) ion
Nickel (II) ion.
What is the atomic number of an element with 24 protons?
Chromium is one of the most important and indispensable industrial metals because of its hardness and resistance to corrosion. Chromium is a chemical element with atomic number 24 which means there are 24 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.
How many protons neutrons and electrons are in an electrically neutral atom?
Chromium-52 is composed of 24 protons, 28 neutrons, and 24 electrons. Chromium-53 is composed of 24 protons, 29 neutrons, and 24 electrons. Chromium-54 is composed of 24 protons, 30 neutrons, and 24 electrons. The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus.
How many protons and neutrons are in a potassium atom?
The first sample is potassium, with 19 protons and 19 neutrons in each atom; it is the lightest. The second is also potassium with 18 protons and 22 neutrons in each atom; it is slightly heavier.
