Answer: what the hell does that mean
Explanation:
Atomic number is the number of protons in the element's nucleus.
The atomic mass number is the number of protons plus the number of neutrons in the nucleus.
Different isotopes have the same number of protons but different number of neutrons
If earth didn't rotate the global winds would stay on the same speed of rate because the wind isn't moving without rotation in the earths axis.
First, we write the atom with 24 electrons. Atoms are neutral, so their electrons and protons are equal in number. The element with proton number 24 is chromium.
Next, a manganese atom has 25 electrons, so if it forms a cation with a +1 charge, it will have 24 electrons. Similarly, if an iron atom which normally has 26 electrons forms a +2 charge cation, it also has 24 electrons. The three symbols are:
Cr
Mn⁺¹
Fe⁺²
The bond angle of bonds in an octahedral molecule is 90 degrees
