What atom has 4 protons and 4 neutrons?
Beryllium
Can an atom have 12 electrons?
Answer Expert Verified So atomic number of element is 12. In neutral atom, number of protons = number of electrons[ as atom is electrically neutral]. conclusion: It is not possible in a neutral atom to have 12 protons and 13 electrons.

Why do atoms have no overall charge?
An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. The nucleus of an atom contains protons and neutrons.
Which species has 9 electrons?
The element fluorine has 9 protons and 9 electrons.
What does the number 19 represent in 19 9 F?
In general atoms are electrically neutral. Therefore the number of protons must equal the number of electrons. In some atoms the number of protons is also equal to the number of neutrons. The atomic number of fluorine is 9 and its mass number is 19.
When electrons are lost a ion is formed?
Forming an Ion An atom that loses one or more valence electrons to become a positively charged ion is known as a cation, while an atom that gains electrons and becomes negatively charged is known as an anion.
How many electrons are in potassium 37?

Is potassium 40 radioactive?
Potassium-40 (40K) is a naturally occurring radioactive isotope of the common element potassium (potassium represents about 2.4% by weight of the earth’s crust). The half-life of 40K is 1.248 x 109 years [1] its origins are primordial. 40K has an atomic percent abundance of 0.0117%.
What is the number of protons of potassium 37?
Why potassium 41 is unstable?
This difference is enough to make potassium 40 unstable. The reason for this is that protons, like neutrons, like to exist in pairs in a nucleus. Potassium 40 contains odd numbers of both – 19 protons and 21 neutrons. As a result it has one bachelor proton and one bachelor neutron.
Is potassium 40 dangerous?
There is really no danger from the radiation coming from the 40K that makes up only 0.012% (120 ppm) of the total amount of potassium found in nature. Potassium-40 decays by electron capture and beta decay. The radiation from potassium-chloride is not much more radioactive than natural background radiation.

Is chlorine-37 radioactive?
There are only two stable isotopes: 35Cl and 37Cl with respective proportions of 75.76% and 24.24% (Berglund and Wieser 2011). The longest-lived radioactive isotope is 36Cl (half-life of 301,000 years); all other isotopes having half-lives of less than 1 h.
Is CL 37 radioactive?
There are two stable isotopes, 35Cl (75.77%) and 37Cl (24.23%), giving chlorine a standard atomic weight of 35.45. The longest-lived radioactive isotope is 36Cl, which has a half-life of 301,000 years….List of isotopes.
