The number of electrons, protons and neutrons in a species are equal to 18,16 and 16 respectively. If the number of electrons, protons and neutrons in a component is 18, 15 and 16 respectively, denot The number of electrons,protons, neutron in a species are 18,16 and 16 respectively.
Assigns proper The number of protons, electrons and neutrons in a species are equal to 17,18 and 18 respectively. Which of the following elements possesses 16 electrons and 16 neutrons?

The sub script to the left corresponds to the atomic number, which is the number of protons and electrons so long as it is neutral. And all of these in this question are neutral and then 15 corresponds to the number of protons, plus the number of neutrons.
So to determine the number of neutrons, we simply need to subtract thes two numbers. So we have seven protons and electrons and then 15 minus seven or eight neutrons, and we just do that with all of them. So for 16 has 16 protons and electrons and 33 minus 16 or 17 neutrons. Copper 29 has 29 protons and electrons and then 63 minus 29 or 34 neutrons and then strontium with an atomic number of 38 has 38 protons and electrons and then 84 minus 38 or 46 Neutrons.
Bury him with 56 as its atomic number has 56 protons and electrons because it's neutral has the same number of electrons, protons and then minus 56 or 74 neutrons and then tungsten with 74 as its atomic number has 74 protons and 74 electrons, and then minus 74 or neutrons.
And the last one is mercury, with 80 protons and 80 electrons, then to minus 80 or neutrons. Chemistry is the science of matter, especially its chemical reactions, but also its composition, structure and properties.
Chemistry deals with atoms and their interactions with other atoms, and particularly with the properties of chemical bonds.
Chemistry also involves understanding the properties and interactions of individual atoms and molecules for use in larger-scale applications. In chemistry and physics, matter is any substance that has mass and takes up space by having volume. All everyday objects that can be touched are ultimately composed of atoms, which are made up of interacting subatomic particles, and in everyday as well as scientific usage, "matter" generally includes atoms and anything made up of them, and any particles and objects that act as if they have both rest mass and volume.
However it does not include massless particles such as photons, or other energy phenomena or waves such as light or sound. Z , the atomic number is the number of protons, positively charged nuclear particles.
How did I know this? Well, I have access to a Periodic Table which lists all known elements according to atomic number. There should be a Periodic Table beside you now! Which element on the periodic table has a total of 16 protons?
