What determines the atomic number of an atom? A. Number of electrons in the other shell. B. Mass of the atom. C. The number of neutrons. D. The number of protons. E. The number of protons plus neutrons. How many neutrons does elem...
If an atom with a mass number of 202 has 122 neutrons, it is an atom of which element? What determines the atomic number of an atom? What element has 6 protons, 8 neutrons, and six electrons? What element has 4 protons 5 neutrons and 2 electrons?
Protons supply the positive charge, and each element has a different number of them. The number of protons in the nucleus determines the atomic number of an element. It's different from atomic mass or atomic weight, which take into account the presence of neutrons. Every atom of a given ...
It is the number of protons that determines the atomic number, e.g., H = 1. The number of protons in an element is constant (e.g., H=1, Ur=92) but neutron number may vary, so mass number (protons + neutrons) may vary. The same element may contain varying numbers of neutrons; ...
an atom. Another big reason it matters is because the modern periodic table is organized according to increasing atomic number. Finally, the atomic number is a key factor in determining the properties of an element. Note, however, the number of valence electrons determines chemical bonding ...
In almost every element, protons are accompanied byneutrons. The only exception is the nucleus of the simplest element, hydrogen. Hydrogen contains only a single proton and no neutrons. The number of protons in anatomdetermines its atomic number in the Periodic Table of Elements. The number of ...
When an atom reacts, it can gain or lose electrons, or it can share electrons with a neighboring atom to form a chemical bond. The ease with which an atom can gain, lose or share electrons determines its reactivity. Atomic Structure ...
We now know that atomic number (the number of protons in the nucleus), not atomic mass number (the number of protons and neutrons), determines chemical behavior.Mendeleyev went further than Meyer in another respect: he predicted the properties of six elements yet to be discovered. For example...
The valency of oxygen (2) and hydrogen (1) determines the H2O formula for water. 7 Valence Another term for valency Valency The combining power of an element, especially as measured by the number of hydrogen atoms it can displace or combine with Carbon always has a valency of 4 Valence Th...
Whether you’re using a manual or automated process, you’ll perform one or more of the various aggregation methods below. Summation:Adds up numerical values to calculate a total or aggregate value. Counting:Determines the total number of data points in a dataset. ...
