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?
Which element forms an ionic compound when it reacts with lithium? What is the most common isotope of lithium? Which element has the highest electron affinity among halogens? Does lithium have metallic bonding? What is lithium's state of matter?
What characteristic of an element determines its specific isotope? What elements are found in the biosphere? What chemical elements are essential in nuclear power? What is formed when elements of matter are chemically combined? What element makes glowing signs?
A component of an atomic nucleus, either a proton or a neutron. Every nucleus consists of nucleons. 10 Nucleus Defined by its number of protons, which determines the chemical element. An iron nucleus has 26 protons. 11 Nucleon Exhibits properties such as mass and charge (in the case of pr...
carries a net positive charge and is called a cation. An ion with more electrons than protons carries a net negative charge and is called an anion. The number of neutrons doesn't come into play since they are electrically neutral. Changing the number of neutrons determines the isotope. ...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that ...
An atom's proton number is its atomic number on the periodic table and determines the identity (name) of the element. Some atoms can gain or lose neutrons while continuing to happily exist, but if a nucleus loses or gains a proton instead, it's a game-changer, because now whatever the...
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 ...
hydrogenatoms have one andoxygenatoms have eight. The number of protons in an atom is referred to as the atomic number of that element. The number of protons also determines the chemical behavior of the element. Elements are arranged in thePeriodic Table of the Elementsin order of increasing ...
What is the difference between Kirat Hundle 1. What is the difference between an element and a compound? An element is an isotope made of the number of neutrons it has. A compound is a substance made of two or more different elements (a mixture). 2. What is the ...
