N=9.933
Explanation:
no of mole = m÷mr
then ,no of molecules=n×la
Answer:- The charge is +2.
Explanations:- Z stands for atomic number. The Z is given as 25 means the atomic number of the element is 25. It has 23 electrons. For a neutral atom the number of electrons is same as the atomic number. Since the number of electrons is less than atomic number, the atom must have lost the electrons.
Number of electrons lost = 25 - 23 = 2
If the element lost electrons then it has positive charge. As, the electrons are lost, the charge is +2.
Answer: it will increase the strong nuclear force in the nucleus
Explanation: Labster
Answer:
The ratio of the mass of an adult rhino to the mass of a small egret is
(1400 kg)/(0.76 kg) = 1842.11
The ratio of the mass of a proton to the mass of an electron is
1836.15
The two ratios are very similar, the ratio of the masses of the proton to the electron being slightly smaller.
