What determines the chemical properties of an element? How can electronegativity cause a covalent bond to be polar? Which element has the highest electronegativity? What one characteristic of an atom determines what type of element it is?
The atomic number of an atom is determined by: ___ A certain atom has an atomic mass of 19 and atomic number of 9. Using a periodic table, what element is this? If the atomic number of an element is 12 and the atomic mass is 25: a. How many protons are there in the nucleus...
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; ...
Determines atomic number and element identity. Influences chemical properties and bonding. 15 Relative Mass Much heavier than electrons. Much lighter than protons. 7 Compare with Definitions Proton One of the determinants of an atom's identity. Changing the number of protons in an atom changes the...
A nucleon is a collective term for protons and neutrons inside an atomic nucleus, while the nucleus is the core of an atom, containing nucleons and thus most of the atom's mass.
How to Know If an Element Has a Positive or Negative... How Many Valence Electrons Does Sodium Have? What is a Polyatomic Ion? What is an Ionic Compound? Why Is Carbon So Important to Organic Compounds? What is a Monatomic Ion? What Determines Whether an Ion Will Form? What...
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 ...
Answer and Explanation:1 The arrangement of atoms within a molecule is called the molecular structure. The molecular structure varies depending upon which atoms are in the... Learn more about this topic: Fats | Definition, Structure & Function ...
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?
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 ...
