A cation has a smaller atomic radius compared with the neutral atom.
Potassium has the largest atomic radius.
The atomic radius gets larger toward the bottom left of the Periodic Table. In general, the radius gets smaller as you go from left to right across the same period and the radius gets larger as you go from top to bottom down the same group.
The atomic number of helium (He) is 2. When He gains one electron to become He plus, it becomes an ion with a net charge of +1, but the atomic number remains the same as 2.
The atomic number of F (fluorine) is 9 and the atomic number of Na (sodium) is 11. Adding them together gives 20, which is the atomic number of calcium (Ca).
The Na+ will have a larger size (atomic radius) while Mg2+ will have relatively smaller size. Both elements have lost their valence (outermost) electrons and achieve a stable octet state as ions. what makes a difference is the effective nuclear charge. because Mg has a higher nuclear charge, the valence electrons are pulled more towards the nucleus thereby reducing the atomic radius.
Potassium has the largest atomic radius.
Na atom has a higher atomic radius compared to Na+ ion. This is because Na+ ion has lost an electron, leading to a decrease in electron-electron repulsion and a smaller electron cloud, causing the ion to have a smaller atomic radius than the neutral Na atom.
The first and third are quadratic expressions in x, the second is a quadratic expressions in n, and the fourth is a quadratic expressions in y. None of them are equations so cannot be solved.
5x^2(x^2 + 5)
231 + 231 = 2 x 231 = 232
The radius of the nth orbit in the Bohr model is given by the formula: (r_n = 0.529 \times n^2 / Z), where n is the principle quantum number and Z is the atomic number. For He+, Z = 2 and n = 3, so the radius of the third orbit of He+ would be (r_3 = 0.529 \times 3^2 / 2 = 2.117 Amstraum).
The neutral atom of potassium has the largest radius.
You fail SO badly. If we have x^4, the 4 is the exponent- the power to which a number is raised. It can be positive or negative.
The atomic radius gets larger toward the bottom left of the Periodic Table. In general, the radius gets smaller as you go from left to right across the same period and the radius gets larger as you go from top to bottom down the same group.
A potassium atom has 19 protons and 19 electrons, plus 20-22 neutrons. A rubidium atom has 37 protons and 37 electrons, plus 46-50 neutrons and so is bigger.
The radius will depend on the plus or minus value of 10 or whether or not it needs a plus sign but the center of the circle is at (-2, 3)
Ninth degree. Nine is the highest exponent.
