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 is 2
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.
Hydrogen plus atomic number?
The atomic number of hydrogen is 1.
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 has a higher atomic radius then Na+, since it still has it's outer electron (3s).
The radius of the first Bohr orbit of hydrogen atom is 0.529 AmstraumThe radius of the third orbit of He plus will be?
Radius of 'n'th orbit of hydrogen like species of atomic no.'z'
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 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 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
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 changes in atomic number and mass number occur in beta emission?
Electron (beta minus) decay: the atomic mass remain approx. constant, the atomic number will be greater with 1 Positron (beta plus) and electron capture decay: the atomic mass remain approx. constant, the atomic number decrease with 1 Double beta decay: the atomic mass remain approx. constant, the atomic number will be greater with 2
What is the atomic number of He plus?
the atomic number is 2
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.
