What usually forms a covelent bond and has 5 valence electrons and has the highest atomic mass in its group?
An atom that forms a covalent bond has 5 valence electrons and the highest atomic mass in its group is phosphorus (P).
Does the valence electrons equal the number of protons?
No, the number of valence electrons does not necessarily equal the number of protons in an atom. The number of valence electrons is determined by the group number of the element in the periodic table, while the number of protons is the atomic number of the element.
What element has 2 valence electrons and more atomic mass than argon?
The element that has 2 valence electrons and an atomic mass greater than argon (which has an atomic mass of about 39.95 u) is calcium (Ca). Calcium is located in Group 2 of the periodic table and has an atomic mass of approximately 40.08 u. It is an alkaline earth metal and is known for its role in biological systems and materials like bone.
Why do you calculate the number of electrons by the atomic mass and number?
You calculate the number of electrons by the atomic mass and number because elements have the same number of electrons as they do protons. The atomic number tells you the number of protons, which is also the number of electrons in a neutral atom. By using the atomic mass to find the number of neutrons, you can determine the overall charge and number of electrons in an atom.
How does an atom of sodium has a larger mass than a atom of neon. how is this possible when neon has so many more valence electrons?
sodium has more protons and neutrons. electrons have practically no mass, valence electrons are just outer orbital electrons. sodium has 11 protons, 11 electrons, and 12 neutrons. Mass is 23. neon has 10 protons, 10 electrons, and 10 neutrons. Mass is just 20. The neon atom has 10 protons and 10 neutrons for a mass number of 20. The sodium atom has 11 protons and 12 neutrons for a mass number of 23. The number of valence electrons has no bearing on mass number or atomic weight.
What usually forms a covelent bond and has 5 valence electrons and has the highest atomic mass in its group?
An atom that forms a covalent bond has 5 valence electrons and the highest atomic mass in its group is phosphorus (P).
What can you predict an element from it's position in the periodic table?
how many electrons it has---how many valence electrons and how many levels of electrons. its Atomic Mass its atomic number
Which element is a metalloid with 4 valence electrons?
Germanium (Ge) Atomic Number- 32 Atomic Mass-72.59
The tendency of an element to react chemically is closely related to what?
its Atomic Mass.
Does the valence electrons equal the number of protons?
No, the number of valence electrons does not necessarily equal the number of protons in an atom. The number of valence electrons is determined by the group number of the element in the periodic table, while the number of protons is the atomic number of the element.
How many valence electrons does hafnium have?
Hafnium has 72 electrons and protons; the number of neutrons is different for each isotope and depend on atomic mass of the isotope.
How you can determine the number of protons electrons and neutrons an atom has from an atom's mass number and its atomic number?
To determine the number of protons, look at the atomic number. The number of electrons is also the atomic number.To find the number of neutrons subtract the atomic number from the Atomic Mass number.
How many valence electrons are there is aluminum-25?
Number of valence electrons depends on number of electrons in uncharged atom(= atomic number), not on mass number. Al has atomic number = 13 and it belongs to group 13( III A) of periodic table so it's uncharged atom has 3 valence electrons. But valence electrons in ions is different. No. of valence electrons in an ion = No. of valence electrons in uncharged atom + negative charge or - positive charge1. 1. for charges only their magnitude is taken i.e. if charge is +2 or -2 then 2 is taken and put in equation.
The chemical behavior of an atom depends upon?
The number of protons, electrons, and neutrons it has, which determine its atomic number, atomic mass, and overall stability. This, in turn, affects its ability to form bonds with other atoms and participate in chemical reactions.
What are some characteristic properties of elements?
Atomic number: Each element has a unique number of protons in its nucleus, known as the atomic number. Atomic mass: The sum of the protons and neutrons in an atom's nucleus determines its atomic mass. Electron configuration: Elements have a specific arrangement of electrons in their atomic shells, which influences their chemical properties. Valence electrons: The outermost electrons of an atom, known as valence electrons, determine how elements interact with other atoms to form compounds.
What information can you gather knowing the atomic number and mass of an element?
If you know the atomic no. and atomic mass, then the no. of electrons, no. of protons and no. of neutrons can also be determined. Atomic No.=No. of electrons = No. of protons. No. of neutrons=Atomic mass-Atomic no. Also, by no. of electrons you can determine its valency and the no. of valence electrons.
How do you determine the numbers of the three types of particles in each atom?
In an atom, no. of protons = no. of electrons=atomic no. no. of neutrons=atomic mass-atomic no.
