It depends on what the element is. But the maximum number of electrons an atom can hold for its second shell is 8
Answer:
207.24.
Explanation:
The mass numbers of the 4 isotopes are 82+ 122 = 204, 82 + 125 = 207,
82 + 124 = 206 and 208.
The approximate atomic mass is worked out by adding the products of their relative abundances and mass numbers:
0.014*204 + 0.221*207 + 0.241*206 + 0.524*208
= 207.24.
Answer:
Neutron - non charged particle in nucleus
nucleus - composed of proton and Neutron
electron - negatively charged particle that moves around the nucleus
proton - positively charged particle in the nucleus.
Explanation:
these the are definitions of the terms
We know that,
acceleration (a) = final velocity(V)-initial velocity(U)/ Time taken(T)
If it’s 22.5 millimeters, it’s gonna be 22,500 micrometers. The answer is C
