Which of the following has the largest radius K plus Na plus Na or K?
Potassium has the largest atomic radius.
What periodic trend does the atomic radius follow?
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.
What is the atomic number of He plus?
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.
What is the atomic number of f plus the atomic number of Na equals the atomic number of this element?
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).
How does the size of a magnesium ion with a 2 plus charge compare with that of a sodium ion with a single plus charge?
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.
Which of the following has the largest radius K plus Na plus Na or K?
Potassium has the largest atomic radius.
What atom has higher atomic radius Na or Na plus?
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.
What is 2x with the exponent 2 plus 3x plus 1. what is 7n with the exponent 2 plus 9n plus 2. what is 3x with the exponent 2 plus 8x plus 5. what is 7y with the exponent 2 plus 19y plus 10?
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.
What is the Factor 5x exponent 4 plus 25x exponent 2?
5x^2(x^2 + 5)
What is 2 exponent 31 plus 2 exponent 31 equals?
231 + 231 = 2 x 231 = 232
The radius of the first Bohr orbit of hydrogen atom is 0.529 AmstraumThe radius of the third orbit of He plus will be?
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).
Does Na plus Na K or K plus have the largest radius?
The neutral atom of potassium has the largest radius.
Is a exponent a number with a plus or - sign?
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.
What periodic trend does the atomic radius follow?
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.
Why does Rb have a greater atomic radius than K?
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.
Center and the radius of the circle x2 plus 4x plus y2 - 6x 10?
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)
What is the degree of the polynomial 5x5 plus 8x2 plus 2x - 3x9 - 8x4 - 4x5?
Ninth degree. Nine is the highest exponent.
