C. 4 decorated cupcakes.
Because 12 divided by 3 = 4, so you can have 4 cupcakes each with 3 cherries
The number of protons and electrons of an atom is equal
and the amount can be obtained by looking at the atomic number of that atom or
element.
The atomic numbers are:
Gold = 79
Thallium = 81
So we are looking for the element with an atomic number of
80, that is:
Mercury
Answer:
<span>Mercury (Hg)</span>
Steroids are biologically very important compounds. They are made up of more that
seventeen carbons. The structure of Steroid is comprised of a fused
cycloalkane ring system. The simplest steroid and the main skeleton of all steroids is
Gonane.
Gonane is made up of four cycloalkane rings i.e. tetracyclic hydrocarbon ring structure. Among these four rings 3 are
cyclohexanes (designated as A, B and C) and one is
cyclopentane (Designated as D). These four rings fuse to form a <span>cyclopentaperhydrophenanthrene.
The Nucleus (Gonane) of steroids along with some derivatives are shown below,</span>
1840 times lesser than
Explanation:
Robert A. Milikan from his experiment found that electrons carry exactly one unit of negative charge and that its mass is 1840 times lesser than the mass of a common hydrogen atom.
- Robert Milikan performed the oil drop experiment and was able to determine the charge on an electron.
- From Milikan's experiment, the relative mass of an electron was discovered to be about 1840 times lesser than the mass of a hydrogen atom.
- A normal hydrogen atom is a proton with an actual mass of 1.67 x 10⁻²⁷kg.
- Electrons weight 9.11 x 10⁻³¹kg which is 1840 less than the weight of a proton.
