I NEED HELP PLZZZZ!!! THANK YOUUUU If an individual proton has mass 1.007825 amu and an individual neutron has mass 1.008665 amu
Drupady [299]

Answer:

1.38269 amu

Explanation:

Gadolinium-157 has 64 protons and 93 neutrons. Recall that mass defect his the difference between the calculated mass and the actual mass of the atom. This difference in calculated mass and actual mass exists because some mass is converted to the binding energy of the nucleus.

Mass of 64 protons= 64 × 1.007825 = 64.5008 amu

Mass of 93 neutrons= 93 × 1.008665 = 93.805845 amu

Mass of neutrons and protons= 64.5008 + 93.805845 = 158.306645 amu

Mass defect= 158.306645 - 156.92396 = 1.38269 amu

Therefore, mass's defect of gadolinium-157 is 1.38269 amu

Which of these elements has two electrons in its outer p orbitals?
ivanzaharov [21]

Silicon (si) has two electrons in its outer p orbitals.

Explanation:

For the element of SILICON, you previously know that the atomic number shows the number of electrons. That indicates there are 14 electrons in a silicon atom. Looking at the design, you can see there are two particles in shell one, eight in shell two, and four in shell three. Si which is 4 elements from the left side of the table,first 2 electrons are s orbitals when next two electrons go to Si
