Can i have some help :'( manganese atom has 30 neutrons and atomic number 25
calculate the atomic mass of manganese atom

The atomic mass of manganese atom : 55

Given

Manganese (Mn) atom has 30 neutrons

atomic number 25

Required

the atomic mass

Solution

The atomic mass=number of protons+number of neutrons

The atomic number = number of protons=number of electrons

The number of protons=25, so the atomic mass :

they begin to vibrate harder causing the material that was solid to turn into a liquid i.e gallium or ice

idk

explanation:
