What is strontiums mass number?
Strontium is a metal element. Atomic mass of it is 88.
What is strontiums state?
solid
How many electrons are their in uranium - 235?
92 electrons - the number of electrons is the same in all the isotopes of uranium. Number of electrons = Number of protons = Atomic number
What determines an element's charge?
The number of protons and electrons in the atom. If the number of protons = number of electrons, it is electrically neutral. If number of protons > number of electrons, it is positively charged. If number of protons < number of electrons, it is negatively charged.
How do you find electrons?
you can find electrons by subtract the atomic number and atomic mass.
How does one determine the number of core electrons an atom has?
subtract the group number from the atomic number
How do you find the number of non-valence electrons?
To find the number of non-valence electrons in an atom, you first need to determine the total number of electrons in the atom by looking at its atomic number on the periodic table. Next, subtract the number of valence electrons, which are the electrons in the outermost energy level of the atom, from the total number of electrons. The remaining electrons, which are not in the outermost energy level, are the non-valence electrons.
How can the number of core electrons be determined on the periodic table?
The number of core electrons can be determined from the periodic table by identifying an element's atomic number, which indicates the total number of electrons. Core electrons are those that are not in the outermost shell; for main group elements, this typically includes all electrons in completed inner shells. To find the number of core electrons, you can subtract the number of valence electrons (the electrons in the outermost shell) from the total number of electrons. For example, oxygen (atomic number 8) has 6 core electrons and 2 valence electrons.
How many electrons does an atom with an atomic number of 20 have?
An atom with an atomic number of 20 has 20 electrons. The number of electrons in an atom is equal to its atomic number.
Can the mass number be used to determine the number of electrons in an atom?
No, the mass number (number of protons and neutrons) cannot be used to determine the number of electrons in an atom. The number of electrons in an atom is determined by the number of protons in the nucleus, which is the atomic number. Electrons are equal in number to protons in a neutral atom.
Are the number of electrons different from every atom of every element?
Each element has a different number of electrons. All atoms of that element have the same number of electrons. The number of electrons is the same as the number of protons.
What is equal to the number of protons which is equal to the number of electrons?
Do you mean what does the number of protons equal? This is the atomic number of the element. All isotopes of an element will have the same number of protons, only the number of neutrons varies.
