Element 34, Selenium, has an atomic mass of about 78.96.
Are coins an element?
No, coins are not an element. Some coins may be made of nearly pure gold, silver, aluminum, or other metal elements, but most present-day coins are made of various metal alloys, often with different composition on the inside than on the outside.
What is the meaning of less than for subsets?
If the symbol is like "< " but rounded , then set A < B means every element of set A is found in set B, but there is some element of set B that is not in A. In words it says that A is a proper subset of B.
What is the ratio of a proton to the mass of a neutron?
The mass of a proton and neutron are pretty close. So the ratio will be roughly 1 to 1 (or 1:1). The neutron is heavier and if memory serves it is exactly the mass of an electron heavier than a proton. Note it takes around 1820 electron to equal the mass of one proton.
Is 8.7-0.26 greater or less than 8?
Less
Why is an aluminum nail less dense than the actual element?
An aluminum nail that is less dense than the element aluminum would not be made of pure aluminum, but would have to be an alloy of aluminum and some other substance. If an aluminum nail is made of pure aluminum, it would have the same density as the "actual" element.
