Calcium, of the alkali earth metal group, has twenty protons and thus an atomic number of 20. The atomic number for an atom is the total amount of protons (positive particles) in an atom. This group comprises the second group according to IUPAC style on the periodic table. Calcium, like the others in its family, is a soft, silverish metal. They are reactive, though not so much as the alkali metals. The electron rings of Calcium are organized 2,8,8,2. The other elements in this family include: Beryllium, Magnesium, Calcium is the third, Strontium, Barium, and Radium.
What else can I help you with?
What is the symbol for an atom that has 20 protons and 22 neutrons?
The atom with 20 protons and 22 neutrons would be Calcium (Ca) with atomic number 20 and mass number 42 (20 protons + 22 neutrons).
What element has 9 protons and 11 neutrons?
The type of element of a particular atom is based solely on its number of protons. An atom with 9 protons has an atomic number of 9, and is (looking on the elemental chart...) fluorine (F).
How many protons are present in an atom with an atomic number of 20?
An atom with an atomic number of 20 has 20 protons.
Which is the symbol for an atom containing 20 protons and 22 neutrons?
Mo (Molybdenum) Atomic number: 42; Atomic Mass: 91
How many protons and electrons does a calcium atom have?
Calcium has 20 protons, 20 electrons and 20 neutrons in its most commonly found isotope.
Which element has 20 protons 20 neutrons and 20 electrons?
Calcium has 20 protons and electrons. The symbol for calcium is Ca and its atomic number is 20.
How many protons neutrons and electrons are in a neutral atom with the symbol 41Ca?
In a neutral atom of calcium-41 (⁴¹Ca), the atomic number of calcium is 20, which means it has 20 protons and 20 electrons. The mass number is 41, which represents the total number of protons and neutrons. To find the number of neutrons, subtract the number of protons from the mass number: 41 - 20 = 21 neutrons. Thus, ⁴¹Ca has 20 protons, 21 neutrons, and 20 electrons.
The mass number of an atom of calcium with 20 protons and 20 neutrons is?
The mass number of an atom is the sum of the protons and neutrons in its nucleus. Therefore, for an atom of calcium with 20 protons and 20 neutrons, the mass number would be 40.
The atomic number for the element calcium is 20 how many protons and electrons does each calcium atom have?
Each calcium atom has 20 protons and 20 electrons. This is because the atomic number, which is 20 for calcium, represents the number of protons in the nucleus of its atom, and in a neutral atom, the number of electrons is equal to the number of protons.
How many protons and electrons are in an atom in calcium?
Calcium's atomic number is 20. That means that it has 20 protons. To make it neutral then, an atom of calcium must also have 20 electrons.
An atom of an element contains 20 protons 20 neutrons and 20 electons This element is?
Calcium: The identity of an element is determined by how many protons each atom of the element has, and calcium is the name of the element with 20 protons per atom.
How many protons (p) neutrons (n) and electrons (e) are in an atom of calcium?
There are 20 p , n , e- in an atom of calcium. Its atomic number is also 20.
