To solve this problem we will apply the concepts related to volume, as a function of length and area, as of mass and density. Later we will take the same concept of resistance and resistivity, equal to the length per unit area. Once obtained from the known constants it will be possible to obtain the area by...Determine the mass of an atom based on its subatomic particles. Consider the element helium. Its atomic number is 2, so it has two protons in its nucleus. Knowing the mass number and the atomic number of an atom allows you to determine the number of neutrons present in that atom by......mass number of an atom is 15, and its atomic number is 7. The atom probably has... at least 15 electrons.about as much mass in electrons as in Two atoms always represent the same element if they have An atom has 6 electrons, 6 protons, and 6 neutrons.

The ion of an element has 3 positive charges.

A. Nanotechnology is the latest breakthrough in technology. It refers to...

The atomic number (7) gives the number of protons, and the mass number is the number of protons plus neutrons. Some questions will include multiple choice options to show you the options involved and other questions will just have the questions and corrects answers.Fundamental properties of atoms including atomic number and atomic mass. The atomic number is the number of protons in an atom, and isotopes have the same atomic number but differ in the number of neutrons.An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across.If the atomic number is 7 this means it has 7 protons in the nucleus. As a result it must have 7 electrons and finally in order to make up the mass the unique question is complicated by way of reality it mixes mass* (amu = 15) and form of debris. it may desire to have centred on atomic huge...Atom: An atom is the smallest unit of matter which retains properties unique to its element. The atom is composed of three subatomic particles- positively charged protons, neutrally charged neutrons, and negatively charged electrons. Atomic number: The atomic number is the number of protons within...
