Which element has 32 protons in its nucleus? If an atom contains 14 protons, it is an atom of which element? Which two particles make up the nucleus of an atom? What region of an atom contains the protons and neutrons? What element with a mass number of 100 has 56 neutrons in its ...
What element has an atomic number of 88?Atomic Number 88:The atomic number of an element refers to the number of protons in its nucleus. For example, carbon has six protons in its nucleus, so it has an atomic number of 6.Answer and Explanation: ...
What is the element from the last electron in its configuration? Give its period and row on the periodic table. a. 1s2 b. 3p5 c. 4d8 Identify the first element on the periodic table. What element in the fourth period of the periodic table has 5 valence electrons?
So, for example, lead has 82 protons and between 120 and 132 neutrons in its nucleus, whereas hydrogen, the lightest element, has just one proton and occasionally one or two neutrons. The number of protons in an atom of any given element is always the same. Physicists call this the ...
Every element has a unique atomic number. This is the number of protons in the nucleus of each atom. What is the atomic number of this helium atom? A neutral atom must have equal numbers of protons and electrons, so the atomic number of an element also gives ...
We will also identify the element represented by X. Step 1: Determine the number of protonsThe ion X2− has a charge of -2, which means it has gained 2 extra electrons compared to its neutral form. Since it has 10 electrons in the anionic form, we can find the number of electrons...
Both the protons and neutrons reside in the nucleus. Protons have a postive (+) charge, neutrons have no charge --they are neutral. Electrons reside in orbitals around the nucleus. They have a negative charge (-). It is the number of protons that determines the atomic number, e.g., H...
Element Chemistry & Physics A substance composed of atoms having an identical number of protons in each nucleus. Elements cannot be reduced to simpler substances by normal chemical means. See Periodic Table. Aspect Appearance to the eye, especially from a specific vantage point "many small unsightl...
Electron has a minimal mass compared to protons and neutrons. The mass of an Electron is so small it's almost negligible. 6 Neutron Neutron can result in different isotopes of the same element. Carbon-14 has two more Neutrons than Carbon-12. 4 Electrons Electron orbits the nucleus in specif...
To be an element, a substance has to at least have protons, since these particles define the type of element. Elements consist of atoms, which contain a nucleus of protons and neutrons surrounded by a cloud or shell of electrons. Elements are considered the basic building blocks of matter be...
