Inertia. The first law of motion is often called the law of inertia. ... Inertia causes a moving object to stay in motion at the same velocity (speed and direction) unless a force acts on it to change its speed or direction. It also causes an object at rest to stay at rest.
Protists are NOT prokaryotes so the answer would be B) False.
8 valence electrons means that the element is stable. When we hear stable, we know the group to look at! Noble gases all have 8 valence electrons making them stable and have a full octet.
Here are some:-
Krypton
Argon
Neon
The method of determining the most common isotope of lead is by determining the average atomic mass. The formula for determining the average atomic mass is:
Substituting the values in the formula:
The most common isotope of lead is:
Lead - 207.22 amu
The atomic symbol of lead is . The atomic number of is 82.
So, the the most common isotope of lead can be written as:
and Lead - 207.22 amu.
